Full textAbstract:
The artist's imagery mainly consists of carrousel horses and reptiles. The only thing that relates the images of the reptiles and the carrousel horses in the artist's work is the fact that she finds both images fascinating and intriguing, but at the same time, finds both of these images some what repulsive and frightening. As a child, the artist developed a fascination for carrousel horses and reptiles. At this time these images mainly inspired feelings of fear in the artist. In the artist's opinion, carrousel horses seem to be frantic and frenzied. The artist feels that this aspect of carrousel horses makes them an image with expressive possibilities and she attempts to capture feelings of fear, curiosity and fascination in her prints. The artist is amazed at the variety of colors and textures found on reptiles. She finds them interesting images because although most reptiles are menacing creatures, they are also beautiful and exotic. The artist feels that this aspect of the reptile makes it an intriguing subject matter to work with.Intaglio is a form of printmaking in which a metal plate, traditionally copper or zinc, is manipulated by certain techniques such as: line etch (where a dry-point needle is used to scratch the surface of the plate onto which hard ground [an acid resistant, waxy substance] has been applied and the plate is etched in acid to incise the lines and form a line drawing); and aquatint (a technique to achieve a wide range of tones in an intaglio print). Aquatint has an appearance similar to that of a water color wash. To create the aquatint tonal areas, powdered rosin is sprinkled evenly over the plate and the plate is then heated until the rosin melts and adheres to the plate. The areas that are to remain white are covered with a hard ground "block out." The plate is etched in acid for a period of time to be determined by the artist and is then taken out and rinsed with water to stop the acid from etching the plate any further. This process is repeated until a desired range of tones are created. Another technique usually used is a hybrid combination of burnishing and scraping using a burnisher or scraper. A burnisher and a scraper are patented tools that are used to polish (burnish) and scrape (that is, cut/remove metal from the plate) the surface of the plate to create highlights, lighten an area, or to totally erase an incised area of the plate. Embossing is another form of intaglio printmaking in which three layers of illustration board are cut to form a positive image on a piece of dampened arches paper that is pressed into the carved image by means of a printing press. The deeper the embossment, the more elevated the image will be on the paper. Pressing the paper down into the layers of illustration board forms an embossed image. No ink is used to create the image. Thus, this form of intaglio printmaking is known as "blind" printing, that is printing without ink.In the artist's work, all of the intaglio techniques discussed are used in combination with each other on the same plate to create a rich image. Researching different techniques has allowed the artist to have a better understanding and appreciation for the intaglio prints of historically renowned artists, who were printmakers before the artist.Department of Art

This project chronicles my explorations of the human figure in intaglio and relief printmaking and in the medium of artists' books. I had very little experience in the field of printmaking prior to my acceptance into the Masters program at Ball State University. I found intaglio, or etching into a metal plate, stimulating and exciting because there are very few limitations in terms of what I can do with this medium. I received a Bachelors of Fine Arts in drawing from SUNY Fredonia. Creating artwork in the printmaking medium has allowed my drawing skills to continue to grow and provided a variety of new technical possibilities. I choose to work with the figure because it is an important subject for an artist to study in order to learn to draw. Since all humans share the same basic structure, it is something that everyone should relate to. It is also something that translates into every possible medium, from cave drawings to fashion design. Many of the artists I have studied, such as Albrecht Durer, and Francisco Goya, worked with the figure in printmaking. Their work provided inspiration while I pursued my own work in this field.Department of Art

Full textAbstract:
The purpose of the Creative Project was to investigate a variety of traditional and contemporary intaglio processes, to relate the processes to other artist's intaglio prints, and to further develop the writer's technical skills by creating a series of intaglio prints using the processes discussed in the research portion of the Creative Project. The Creative Project consisted of a written section containing background information pertaining to technical aspects of the medium and brief discussions of selected works by various artists, and the execution and discussion of a series of prints by the writer using the intaglio techniques separately and in combination with one another.The background information section of the Creative Project consisted of working definitions of technical terms and brief discussions of four prints selected from the Ball State University Art Gallery collection. The prints selected were executed by George Rouault, Susan Rothenberg, Chuck Close, and Jim Dine. The writer also included a brief discussion of some of Stanley William Hayter's contributions to intaglio printing.The execution of the Creative Project resulted in the creation of five intaglio prints. The prints were entitled Highway Aviary, Fish Anatomy, Family, Untitled (Seated Figure), and Dance of the Flightless Bird. Each print utilized different techniques or combinations of techniques on copper and zinc plates. The processes involved in the execution of the prints were engraving, etching, aquatint, mezzotint, and spit biting. The prints were black and white except for the work entitled Fish Anatomy, which was printed with four colors. The print entitled Dance of the Flightless Bird was printed using multiple colors, however the actual edition was black and white. The writer was able to acquire the necessary materials for completion of the project through a grant provided by the Ball State University Office of Research.The completion of the Creative Project resulted in the writer’s improved understanding of intaglio processes and greater technical skills resulting from extensive work in the medium. The Creative Project stressed the importance of intaglio printing in contemporary art and revealed the need for further investigation into experimental techniques in intaglio printing.

Full textAbstract:
L’obiettivo dello studio è quello di determinare le cause della rottura a fatica in un accoppiamento albero–mozzo.
Nella prima parte si cerca di costruire un modello FEM (attraverso Ansys Workbench 12.0) che simuli il comportamento del provino albero-mozzo sottoposto a una flessione alterna, come nella macchina di Moore. Con esso si cercherà di individuare le variabili del problema e quali potranno influenzare la σy_max e il Kt.
Nella seconda parte si cercherà di stabilire se il fretting sia funzione dalle stesse variabili del Kt, se esiste una transizione tra i due fenomeni e la quantità di usura prodotta dal fretting.
Infine si realizzeranno delle prove sperimentali per verificare le ipotesi dedotte dall'analisi FEM.

Lo scopo della presente ricerca è valutare l’idoneità dell’acciaio da utensili innovativo K890, prodotto da Böhler con metallurgia delle polveri, ad essere impiegato per la realizzazione di componenti motore di moto da corsa, quali alberi a camme e a gomiti, in sostituzione dell’acciaio da nitrurazione GKHW, prodotto da Aubert&Duval con processo ESR (Electro Slag Remelting). Lo studio è stato condotto a valle di una precedente sperimentazione condotta su provini non intagliati ed ha previsto l'esecuzione di prove di trazione e prove di fatica a flessione rotante con intaglio oltre a prove di durezza ed analisi microstrutturali e frattografiche.
Sono stati testati due lotti di acciaio K890, aventi durezza di 752 e 821 HV rispettivamente. Durante i test di fatica il lotto in K890 a durezza maggiore ha mostrato un limite di fatica con intaglio superiore al GKHW nitrurato. I risultati ottenuti sui due lotti di K890 sono stati impiegati per valutare l’applicabilità di relazioni empiriche per la stima del coefficiente di concentrazione a fatica delle tensioni ad acciai ultra-alto resistenziali. E’ emerso che le relazioni più tradizionali sovrastimano l’effetto dell’intaglio per questa tipologia di acciaio. A conclusione dello studio, considerando l'esito delle stesse prove condotte sull'acciaio GKHW nitrurato attualmente in uso, si può affermare che l'acciaio K890 è un possibile candidato per la produzione di alberi in ambito racing.
La disamina dei risultati sperimentali è preceduta da tre capitoli incentrati su un inquadramento teorico, derivanti da ricerche bibliografiche: il primo riporta un’introduzione al funzionamento ed alle caratteristiche degli alberi a camme e a gomiti; il secondo è relativo alle proprietà degli acciai da utensili tradizionali ed innovativi; infine il terzo riguarda una trattazione sul danneggiamento da fatica, con particolare riguardo all’effetto dell’intaglio ed alle caratteristiche del fenomeno negli acciai ultra-alto resistenziali.

Full textAbstract:
This thesis presents a novel approach to printmaking theory and pedagogy, focusing in particular, on the intaglio hardground process. It is a qualitative study that gives an account of a group of second year graphic design students who encounter the hardground process for the first time. A multimodal social semiotic framework is utilised to shed light on the meaning-making practices related to intaglio hardground. This can be a somewhat deterministic process which is hindered by conventions and constraints. This research explores a metalanguage for the intaglio hardground process. This metalanguage is explicated by addressing the practical processes involved during the intaglio process, interrogating the semiotic resources that are available during this process, and the pedagogic practices within the printmaking studio. Meaningmaking is also explored in terms of how students employ the semiotic resources as coping mechanisms when coming to terms with the conventions and constraints associated with the intaglio hardground process. Process-driven disciplines like intaglio hardground are convoluted and the semiotic resources assist the students to navigate between the technical and the creative process of intaglio hardground. The argument is that students engage with semiotic resources according to their needs, in other words, their interest determines the use of semiotic resources at their disposal. The findings show that each student follows a unique and sometimes, unconventional path during the meaning-making process. These different paths to meaning-making encourage students to explore and take ownership of the semiotic resources that they utilise, as well as their own meaningmaking experiences.

Full textAbstract:
Consumerism and Death are both very political and ever present in our lives. Violence and death are seemingly on the rise, coinciding with the use of media as a distraction. It seems as though every time there is a catastrophic event, the president takes to social media to pick fights or make outlandish claims to distract the people from what is truly happening. Consumption of physical goods is another fixation heightened by the media and celebrities. For the average human, keeping up with social trends is the thing to do, and there is such a quick turn around with what item is considered “hot”. This way of living leads to mass production, leading to mass consumption, ending with mass waste. This societal residue of consumption is pushing us ever closer to mass extinction and we can’t seem to kick our wasteful habits.
All of my work for my MFA show will be like encountering an ooey-gooey shiny glitter coated acid bomb. The viewers will be drawn in with the sweet scent of sugary treats and hypnotized by the bright sun-shiny colors, only to realize they’ve been distracted and an acidic tinge lingers in the air. The dark rippling undertones start to reveal themselves to the audience and suddenly we realize that it's not all fun and games. Behind the bright colors are dark truths ready to spew some truth juice into your blissed out mindset.

Full textAbstract:
This research into intaglio printing, its materials and
techniques, deals with the three main conservation
problems specific to the process. They are: acidity of
the paper, buckling and/or tearing along the printed edge
of the plate caused by excess pressure during printing,
and yellow/brown staining, or halo, around the printed
image. Research done in the cause of this study reveals
that these problems are not confined to contemporary
printmaking practices, as believed by some conservators,
but can be traced back to the historic beginnings of the
Intaglio Printing.
The results of the analyses and tests performed in this
investigation indicate that these problems can be
partially, if not completely, eliminated by simple and
inexpensive improvements to the process of printing.
1 - An alkaline solution, used to dampen the paper prior
to printing, will act as a buffer, making the paper
resistant to future attack from acids. Importantly, it
will also accelerate the drying of the ink, which is
essential to the production of a thick solid ink-film.
2 - Excessive pressure during printing destroys the
natural resilience of the paper within the printed area
and should be kept to a minimum. Plates that have not
been bevelled sufficiently can also be very harmful to
the paper, cutting and/or tearing paper fibres. These
problems are not visually evident after printing, but are
ultimately very detrimental to the life of the print.
3 - The traditional method of drying prints, between
blotters and under weight, is a major cause of the
yellow/brown staining, or halo, formed around the printed
image. The vehicle in the ink, a product of linseed oil,
normally dries by polymerization and oxidation reaction
with oxygen from the atmosphere. Press-drying retards this
reaction causing the paper to absorb part of the vehicle.
Air-drying accelerates the drying process, producing a
much thicker and stronger ink-film and reducing absorption
of the vehicle into the paper. Although air-drying will
produce buckling, this can be easily remedied after seven
days by dampening the print and press-drying.

Full textAbstract:
In 1987, to avoid working with hazardous traditional materials, I began to research with the aim of developing safer and more environmentally friendly printmaking systems for artists. I studied the history of innovation to identify principles; analysed theory and practice; identified risks; selected criteria; researched classical, traditional and new methodologies; revised classification and terminology; identified gaps in the projected systems; developed water-based materials for acrylic-resist etching, screenprinting and autographic positives; created new systems for water-based screenprinting, etching, collagraphy and other intaglio methods; tested these through teaching artists and co-publishing with high-profile artists; revised teaching and learning; documented the research; and wrote and illustrated two pedagogic books to disseminate the research. The results of the research have been the creation of coherent printmaking systems designed for artists; the manufacture by Lascaux of eighteen new water-based materials for printmaking; the exhibition of works made using the systems; and the publication by Thames & Hudson of the books. These definitive books explain why there was a need for change; how the systems are as user and environmentally friendly as is currently possible; how the principles remain true to classical and traditional theory; how to use the new systems; and how effective and versatile the systems are; and they also demonstrate the many creative possibilities. The research has made a significant contribution to knowledge and has been influential in the worldwide move towards the modernisation of printmaking. The systems and terminology such as acrylic-resist etching (ARE) and photocollagraphy are increasingly used in art colleges and print studios. The research continues to be disseminated and validated through the international availability of new products; the creating, exhibition and purchase (for major collections) of prints made using the systems; and by documentation online, in artists’ catalogues, and in my books and those written by other authors.

Linking his thematic inspiration (the strange, the bizarre, the weird and the odd) to his artistic reflection, Lopez conceives of his work as based on his fascination with human facial expressions. "It is there where it is born", he says. Like Leonardo, he believes that the eye is the superior organ. Lopez's use of form and color represents his main objective: to show emotion, humanity and elegance. For that, it is necessary for him to reveal character as well as beauty. It is again, the approach used by the great masters such as Leonardo, Velázquez, Géricault and Goya in representing integrity inside the strange, the bizarre, the weird and the odd. Lopez's art invites the viewer to stare at it, to establish a cordial exchange and to venture into the fascinating world of the unusual.M.F.A.

Dissertation submitted in partial fulfilment of the requirements for the degree
Master of Technology: Graphic Design in the Faculty of Informatics and Design at
the Cape Peninsula University of TechnologyThis study investigates the application and use of the latest graphic design software technologies to help plan and ideate the intaglio printmaking process. This is significant as intaglio is a 600 year old process which has evolved little, if any, in the last few hundred years although it was born from technology. Furthermore, the intaglio process relies on mental visualisation of the final artwork, making the real outcome and the planned outcome dissimilar. Students of intaglio printmaking are often surprised or disappointed by the printed result due to the lack of efficient planning. There are several ways in which software influences the creative process, including enhancing visualisation and communication, premature fixation, circumscribed thinking and bounded ideation. In this research, computer software is used as a simulator to facilitate the planning process in order to minimise the disconnect between visualisation and outcome, and serve as learning instrument. The use of digital computer technologies has been a highly debated issue in printmaking as there exists a rift between printmakers; those who embrace and explore new technologies and those who reject new methods in favour of traditional means. New technologies in printmaking offer exciting opportunities, both innovative and creative, but these new technologies are often seen as alternative or auxiliary methods of printmaking compared to traditional ways. Since these debates have been buried but not necessarily resolved, this study reinvigorates some of these perspectives and seeks a common middle ground. This study does not argue for, or against computer technology, but rather for a third paradigm: technology can coexist with intaglio without compromising the beauty and authenticity of hand processes. Computer technologies, therefore, serve as a facilitator to amplify the traditional intaglio hand process. However, the issue of discussion in this thesis is not hybrid printmaking but rather a hybrid mode of thinking in the printmaking discipline. This iterative design experiment consists of a written dissertation and intaglio printed artworks which inform and complement each other. The theoretical foundation of the art practice is found in the Bauhaus slogan: “Art and technology: a new unity”. Art and technology form the basis of the theory and the theme of entropy – the process of degeneration – is illustrated in the design artefacts. This theme shows process and illustrates the idea of a positive agent: the interference of computer in intaglio to instil new energy and value not only to keep it alive, but position it as an important skill necessary for growth in the knowledge-based economy. Furthermore, this study contributes to the scholarly discussion of design’s conceptual skills (ways of thinking) in order to enhance production capabilities (ways of making).

Tradition begins with innovation. The rich and complicated history of Printmaking is shaped by invention and discovery. I see this advancement for the sole purpose to distribute knowledge and ideas to every person regardless of prosperity and status. At its core intention is the need to make art and knowledge accessible. The procedural research I have been exploring along side my artist research was designed to do just as invention in printmaking has done before. I have applied my knowledge and availability of modern technology with traditional ways print artists create. These new processes are geared to make photomechanical practices in lithography and intaglio cheaper and more accessible to artists and students with limited resources. I have also included a statement about the artwork that has been able to be developed because of this research to provide context for my artistic practice.

Full textAbstract:
Abstract
In gravure offset printing, ink is transferred with the help of an offset material from a patterned gravure plate to a substrate. This thesis is concerned with the study and further development of this printing process for electronics; on alumina, glass and polymers.
The work has been divided into five parts. In the first section, the printing process is described. The second section describes the composition of the inks for gravure offset printing and the resulting ink properties. It also presents the ink transfer mechanism; the model that explains how the ink is transferred between an offset material and a substrate. The third chapter details the printing process explained by a solvent absorption mechanism. The forth chapter describes the firing/curing of printed samples and their properties. The last chapter describes applications of the method.
The inks used to produce conductors on ceramics (ceramic inks) and conductors on polymers (polymer inks) contain silver particles, and were under development for gravure offset printing. The major achieved properties were the high ink pickup to the offset blanket and high transfer percentage to the substrate. 100% ink transfer from blanket to substrate for ceramic inks and almost 100% ink transfer for polymer inks was obtained. The printing of ceramic inks was able to produce 8 μm of relatively thick, 300 μm wide lines with < 10 mΩ/sq. resistance. The minimum line width for conducting lines was 35 μm, with one printing. Multi printing was applied producing as many as 10 times wet-on-wet multiprinted lines with 100 % ink transfer from blanket to substrate resulting in a square resistance of 1mΩ/sq. Polymer inks were able produce a square resistance of 20 mΩ/sq. for 300 μm wide lines after curing at 140 °C for about 15 min, and the minimum width was down to 70 μm.
In the optimised manufacturing process, the delay time on the blanket was reduced to 3 s. In addition to ultra-fine-line manufacturing of conductors, the method enables the manufacture of special structures e.g. laser-solder contact pads with 28/28 μm lines/spaces resolution. With industrial printing equipment it is possible to produce 100 m2/h with the demonstrated printing properties.

Full textAbstract:
This project involved a series of linoleum, woodcut, and intaglio prints whose subject matter was derived from my imagination. The inspiration for this work is the ocean and the myriad life forms found there. I perused books on the ocean and created characters from these images. These prints also have a psychological edge and emotional aspect reflecting the state of mind I was in when 1 created them. Putting these ideas together in the intaglio prints as well as using different techniques was the challenge in making this work. My goal was also to explore linoleum and woodcut prints where I used multiple blocks and/or rolled more than one color on a block to achieve a multitude of hues for one image. I found this complex way of making images exciting and feel that the works created have been successfully resolved.Department of Art

Resumo: O presente estudo buscou utlizar o policarbonato, polímero plástico, como matriz de gravura em côncavo. Assim, este trabalho teve como objetivo tomar a gravura em côncavo sob o ponto de vista de sua prática, experimentando técnicas de gravação diretas, indiretas e aditivas, pesquisando também outros procedimentos passíveis de aplicação no policarbonato, explorando desta forma suas possibilidades expressivas. Foram pesquisadas as relações decorrentes da prática da gravura, entre a mão, a ferramenta e a matriz, assim como os aspectos físicos e químicos do policarbonato relacionados a essa prática. Os processos de gravação e impressão descritos nesta pesquisa ressaltam os momentos de aproximação e afastamento dos resultados obtidos na gravura em côncavo tradicional. Ao final, são apresentadas vinte e três estampas produzidas a partir de matrizes em policarbonato.
Abstract: This research investigated the use of polycarbonate, a plastic polymer, as a plate to intaglio printing. The main objective of this research was the approach of intaglio printing from the point of view of its practice, trying on direct, indirect and additive engraving techniques, also searching for other procedures to use on polycarbonate, therefore exploring its expression possibilities. The relation concerning the hand, the tool and the plate on the results of intaglio practice was also researched, as well as the chemical and material aspects of polycarbonate linked to this practice, The engraving and printing process described here shows results obtained from moments of approximation and spacing on traditional intaglio printing. At the end, twenty three stamps made of polycarbonate plates are presented.

Os processos de gravação e impressão descritos nesta pesquisa ressaltam os momentos de aproximação e afastamento dos resultados obtidos na gravura em côncavo tradicional. Ao final, são apresentadas vinte e três estampas produzidas a partir de matrizes em policarbonato.
This research investigated the use of polycarbonate, a plastic polymer, as a plate to intaglio printing. The main objective of this research was the approach of intaglio printing from the point of view of its practice, trying on direct, indirect and additive engraving techniques, also searching for other procedures to use on polycarbonate, therefore exploring its expression possibilities. The relation concerning the hand, the tool and the plate on the results of intaglio practice was also researched, as well as the chemical and material aspects of polycarbonate linked to this practice, The engraving and printing process described here shows results obtained from moments of approximation and spacing on traditional intaglio printing. At the end, twenty three stamps made of polycarbonate plates are presented.

Full textAbstract:
This practice-led visual arts research project explores the implications of modern genetic
technologies through printmaking and the use of genome sequencing as a catalyst to produce
artistic responses. Studio methodologies include the printmaking techniques of laser-cut
woodblock, photo screen-printing and photo-polymer intaglio, and the appropriation of
imagery from a range of sources including, photographs by Eugène Atget and Eadweard
Muybridge, vintage knitting and crochet instruction booklets, and photographs of ancient
Roman artefacts. The written exegesis examines correspondences between contemporary
forms of image appropriation and technologies used for genetic manipulation. The project is
contextualised by surveying contemporary visual artists working with relevant printmaking
techniques and addressing similar themes.
The biological sciences have been impacted and, in some cases, transformed by advances in
genomics, and the science of genomics has itself been transformed by the integration of the
biological with new digital visualisation technologies. These recent advances have generated
a range of responses from contemporary artists and enlivened debate within Post- and
Transhumanist discourses. Artists engaging with these new digital representations are often
motivated to reassemble the fractured body, highlighting both the reductionism inherent in
the process and the potential misuses of these technologies. The ubiquitous presence of
appropriation within contemporary art provides an analogous structure for envisioning the
possible applications of new biological technologies.
This research examines some important correspondence between the visual image and
genetic technologies that are revolutionising many aspects of life in the twenty-first century.
These relationships include: the digitisation of images and genetic data; the use of digital
technologies to manipulate images and genetic data; utilising DNA synthesis for data/image
storage; and the role image recognition technology plays in the development of artificial
intelligence. Image theorists Barbara Maria Stafford, Nicolas Bourriaud, and W.J.T. Mitchell
inform this research and a range of Post- and Transhumanist theory is surveyed and critiqued.Thesis (PhD Doctorate)

Full textAbstract:
In questa tesi di laurea si affronta il problema della resistenza meccanica nei riguardi di un fondamentale componente presente in tutti i motori a combustione interna: l’albero a gomiti.
In tutti i motori a pistoni l’albero a gomiti è ritenuto l'autentico "cuore": esso infatti è il componente che raccoglie l'energia meccanica che si sviluppa nei cilindri per inviarla alla trasmissione. Si tratta di un organo estremamente sollecitato dal punto di vista meccanico.
Come tutti gli altri componenti del propulsore, anche l'albero a gomiti ha subito, con l'evolversi della tecnica, una progressiva trasformazione, sia per quanto riguarda il suo dimensionamento e, in minor misura, il suo disegno, che per quanto concerne le soluzioni costruttive impiegate.
L'elaborato introduce gli alberi a gomiti, esponendo le peculiarità, le caratteristiche strutturali e le tecniche di produzione di questo eccezionale componente meccanico; espone il concetto di fatica meccanica e analizza i principali fattori che incidono sulla resistenza a fatica degli alberi a gomito; esamina, in particolare, i parametri costruttivi adottati durante la produzione del componente che consentono di ottenere un’elevata longevità del pezzo e ottime prestazioni meccaniche.
Infine, viene approfondito il concetto d’intaglio, fenomeno che grava in particolar modo sulla vita a fatica dell’albero. Un progettista meccanico, nel calcolo del componente, deve obbligatoriamente tenere conto delle concentrazioni di tensione dovute alla forma geometrica dello stesso: verrà, quindi, effettuata un’analisi agli Elementi Finiti per valutare l’effetto dell’intaglio e le soluzioni da adottare per limitare il più possibile il fenomeno di concentrazione delle tensioni.

Full textAbstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThis research explores metal sheet carving from the technique of intaglio. Each "trampled object" is inspired by the study of medieval illuminations images (from the tenth century to the fifteenth century), where the ornament is the focus of artistic creation. In this dissertation, I present my understanding of the term "intaglio" and I define my plastic work as "trampled objects" because using the nomenclature "matrix" requires a series of procedures that are ignored by me at the moment, namely, the imprinting of copies. However, I develop the technique of intaglio using metal sheets of copper and yellow brass, which are displayed directly to the public, in other words, without the traditional pattern of the resulting imprinting. Contemporary visual artists who also exhibit metal sheets [Laurita Salles (1952), Ana Alice Francisquetti (1955) and Otilia Carrique (1954)] are quoted and used to point out the central question guiding this research: the possibility of making metal sheets, which were seen as part of the process of intaglio, come to aesthetics fruition. I briefly comment on some relations of illuminations with the work developed, as it is inspired by medieval ornaments. I analyze some points of interest in the history of illumination and also comment on some contemporary paradigms of art from the thought of Yves Michaud (2008) mainly. Finally, I display to the reader the works developed during this survey. I also broach about the technical elaboration of the works, reporting all the way traced in the atelier, and argument on each of the four sets of engraved objects created (Pequenos Portais, Detalhes Iluminados, Citações Medievais and Filigranas), comparing them to images of some illuminations studied.
Esta pesquisa explora a gravação de chapas metálicas a partir da técnica da gravura em metal. Cada objeto gravado é inspirado no estudo de imagens de iluminuras medievais (desde o século X até o século XV), onde o ornamento é o foco da criação plástica. Nesta dissertação, apresento a investigação sobre o termo gravura e catalogo os trabalhos desenvolvidos como objetos gravados , pois aderir à nomenclatura matriz requer uma série de procedimentos que não são salientados neste momento, a saber: a impressão de cópias. Todavia, desenvolvo na técnica da gravura em metal a gravação de chapas de cobre e latão amarelo que são expostas diretamente ao público, ou seja, sem a tradicional estampa resultante da impressão. Algumas gravadoras contemporâneas que também trabalham com a exposição de chapas de metal são citadas: Laurita Salles (1952), Ana Alice Francisquetti (1955) e Otilia Carrique (1954), através delas aponto a questão central norteadora da pesquisa, que é a possibilidade de fruição estética através da materialidade das chapas metálicas que antes eram vistas apenas como uma etapa do processo da gravura. Brevemente, comento algumas relações das iluminuras com o trabalho desenvolvido, já que este é inspirado nos ornamentos medievais. Analiso alguns pontos de interesse na história da iluminura e alguns paradigmas contemporâneos da arte a partir do pensamento de Yves Michaud (2008), principalmente. Por fim, apresento os trabalhos desenvolvidos durante a pesquisa, discorro sobre o processo técnico de elaboração das obras, relato todo o percurso traçado em ateliê; e argumento sobre cada uma das quatro séries de objetos gravados criadas: Pequenos Portais, Detalhes Iluminados, Citações Medievais e Filigranas, comparando-as, em alguns momentos, com as imagens de algumas iluminuras estudadas.

Full textAbstract:
Nombreux sont les artistes plus ou moins reconnus qui travaillent pour le compte de l’administration postale depuis 1928, année d'émission du premier timbre-poste français gravé en taille-douce. Cette technique, devenue le procédé par excellence de création des timbres-poste en France, se développa et connut des temps forts avec les années 1930 et jusque dans les années 1970. Tous les timbres-poste, à quelques rares exceptions, sont alors gravés par des artistes. Peu à peu, l’apparition de nouveaux procédés de fabrication, tels que l’héliogravure, l’offset et la gravure assistée par ordinateur, s’impose à la taille-douce traditionnelle. Aussi, le poinçon, plaque en acier qui sert de support au graveur, est progressivement remplacé par des procédés électromécaniques et photochimiques permettant d’obtenir des délais d’exécution et des coûts de fabrication bien moindres et sans doute mieux adaptés à des productions industrielles. Cette étude présente une analyse de l’évolution de l’art de la gravure, de sa place et de son rôle dans le domaine de la philatélie durant une période précise, de 1928 à nos jours. Le statut de l’artiste graveur et sa reconnaissance artistique évoluent au même titre que changent le statut de l’administration postale, sa politique et ses besoins liés aux exigences économiques du marché. L’examen approfondi des créations philatéliques, commandes régies par un cahier des charges strict ainsi que des conditions de travail et de l’investissement des graveurs de timbres face à leur métier, a permis de présenter les particularités esthétiques et plastiques de leurs travaux et de leur attribuer une place dans le domaine de l’artMany artists, some more famous than others, have worked for the postal administration since 1928, the year of the first issue of an engraved French postage stamp . This technique, which became the most important method of creating postage stamps in France, developed and reached a peak in the 1930s and continued until the 1970s. During this time all postage stamps, with few exceptions, were engraved by artists. Gradually, however, the emergence of new manufacturing processes, such as heliogravure, offset printing and computer-aided engraving, replaced traditional engraving. Also, the stamping device, a steel plate that served as a support for the engraver, was gradually replaced by electromechanical and photochemical processes making it possible to obtain much lower turnaround times and manufacturing costs and was probably better suited to industrial production. This study presents an analysis of the development of the art of engraving, its place and its role in Philately during a specific period, from 1928 to the present day. The status of the engraver and his artistic recognition changed along with the status of the postal administration, its policy and its needs in response to the economic demands of the market. The in-depth review of philatelic creations, orders governed by strict specifications, working conditions and the investment of stamp engravers in their craft, has made it possible to show the aesthetic and plastic features of their work and secure them a place in the art world

Дисертаційна робота присвячена встановленню закономірностей впливу технологічних факторів металографічного друку на якість відбитків. Для виконання роботи було використано профілометричні методи дослідження поверхні зразків (механічна, оптична профілометрія); мікроскопічні методи дослідження поверхні та мікротомних зрізів зразків; органолептично-експертний метод тактильної дискримінації зразків; експертний аналіз якості зразків.

The peculiarity of this printing method is the possibility to form the strokes with different ink layer thickness (up to 320 microns) on the prints. It provides identification of the authenticity of the strict accounting documents by the public, including visually impaired people. But there is the paucity of theoretical and practical developments regarding the intaglio printing. Thus, the determination of the principles of the ink layer formation and its dependence on the influence of technological parameters of the process to provide high quality of intaglio printing is an topical scientific and technical task. The dissertation is devoted to establish the regularities of the influence of the intaglio printing technological factors on the prints quality. The generalized hierarchical model of prints quality forming, based on a detailed analysis of professional literature and scientific sources, was developed. A group of quality indicators and the main technological factors that influence prints quality were determined for the generalized hierarchical model of prints quality forming. The phenomenological model of intaglio ink transferring was developed and a mathematical description of physical processes, occurring during intaglio ink transferring, was made. Thus, the basic technological parameters that influence the prints quality were determined. It was found that the most effective factors that influence the quality of the ink relief forming are the geometric parameters of the plate as well as the technological print parameters, such as print pressure and print speed. The model of intaglio ink penetration and its distribution during intaglio printing was created. It allowed to investigate how the pressure that acts throughout the printing contact can influence the ink penetration depth. The modeling of the influence of heat exchange processes and the inertia of the process on the intaglio ink layer formation was carried out. These models explained the cause of asymmetry of the cross-sectional shape of strokes obtained by the intaglio printing. The results of modeling are confirmed by experimental research which was carried out with using of the developed method of determination of the generalized quality index of intaglio printing. The determination of the index is based on surface profilometric and microscopic analyses as well as on organoleptic and visual analyses of prints. The method allowed to increase the objectivity of quality evaluating and detect the regularities of the influence of the technological process parameters on the intaglio prints quality parameters. Based on the experimental study results, it was recommended to use a printing plate with the engraved elements of a rectangular profile or trapezoidal profile with an angle of 75 degrees and the element width to depth ratio of more than 1.3 times. It was also recommended to use reduced printing speed and high pressure in printing nip. The correlation analysis of the dependence of the generalized quality index on technological factors was made. As a result, the ranking of the factors on the weight of their influence was carried out. These conclusions became the basis for the recommendations given to the NBU Banknote Printing and Minting Works. The recommendations were aimed at ensuring the quality of the intaglio printing which is produced by the plates made by direct laser engraving. The system of technological assurance of banknotes quality in the process of intaglio printing was developed. As a basis for the system, the developed software for determining of the dependence of the quality printing parameters on technological factors as well as the software for determining of the ink layer thickness were used. By using this system in the manufacturing it is possible to improve the autonomy of the prints quality control process and to normalize the reproduction.

Full textAbstract:
This project presents and analyses all of the signet rings and intaglios so far unearthed in Roman Britain to reinterpret how they were used and their role within provincial society. These small artefacts have traditionally been regarded as attractive but relatively insignificant minor objets d’art, with little relevance to the wider discourses of Romanists. This thesis attempts a more critical examination of how they were used and their role within provincial Roman society. I argue that signet rings were an essential element in provincial society that should no longer be overlooked. This project builds on the pioneering Corpus assembled by Martin Henig in the 1970s, including more recent discoveries and more than doubling the material available to him. This combined body of evidence includes 2,012 signet rings and intaglios, making it one of the largest contextualised assemblages of these objects ever studied. It also benefits from the results of developer funded archaeology and the advent of recording by the Portable Antiquities Scheme, enabling us to create a richer and more detailed picture how they were used. My approach has been to resituate these objects in terms of the archaeological context in which they were found, but also to consider them as functional as well as decorative objects. When studied in this way signet rings provide a unique perspective on the identity of their wearers, and how they wanted to present themselves to others. I have found growing evidence for the use of signet rings amongst local elites before the Roman invasion of Britain, and it is clear that they had a role to play in negotiating identity after the conquest. I have also been able to identify trends in the way that different communities used signet rings, both as regards their imagery and materiality. It is also apparent that in some parts of Britain these objects remained a feature of a type of dress and the hallmark of a society that remained alien to their inhabitants throughout the Roman period. However, for those who chose to wear them, signet rings could be more than just objects but reflections of themselves.

Full textAbstract:
Lo scopo del presente elaborato è valutare un eventuale effetto benefico della pallinatura sulla resistenza a fatica di due acciai prodotti per metallurgia delle polveri: il K890, prodotto da Böhler e l’ASP2005, prodotto da Erasteel. Quest’attività si inserisce in un progetto volto a valutare l’idoneità di tali acciai innovativi ad essere impiegati per la realizzazione di componenti motore di moto da corsa, quali alberi a camme, in sostituzione dell’acciaio da nitrurazione GKHW, prodotto da Aubert&Duval con processo ESR (Electro slag remelting). Lo studio è stato svolto a valle di una sperimentazione condotta su provini intagliati degli stessi acciai e ha previsto: prove di fatica a flessione rotante, prove di trazione, prove di durezza, misura di tensioni residue, analisi microstrutturali e frattografiche.
Sono stati testati provini in ASP2005, con durezza pari a 869 HV e in K890 di due diverse durezze, pari a 752 e 821 HV, tutti intagliati e pallinati. Entrambi i materiali hanno mostrato un effetto benefico della pallinatura sul comportamento a fatica; i risultati ottenuti sono stati impiegati al fine di valutare l’applicabilità di relazioni empiriche per la stima del coefficiente di concentrazione a fatica delle tensioni e della sensibilità all’intaglio di acciai ultra-alto resistenziali. È stato dimostrato che le relazioni tradizionali sovrastimano l’effetto dannoso dell’intaglio per questo tipo di acciaio nella condizione pallinata.
È stato, inoltre, condotto uno studio per la modellazione del comportamento a fatica di provini intagliati con un coefficiente di concentrazioni delle tensione Kt=3 e in un secondo momento si è tentato di estendere il modello anche a provini con un Kt compreso fra 1 e 3.
Queste analisi sperimentali sono precedute da un inquadramento generale delle funzioni e dei requisiti di un albero di distribuzione in ambito racing e da una trattazione circa i meccanismi di rottura per fatica in acciai ultra-alto resistenziali.

Full textAbstract:
The present document summarized the aims and the results obtained by the candidate, during the Ph.D. programme. The research activity consisted in the investigation of the high temperature fatigue behaviour, considering the effect of the temperature combined with creep. After a preliminary analysis, the investigation of different notches reproducing the geometry of real components was considered a key topic in the present research activity. These geometries, indeed, are completely neglected in the past and recent literature, despite their important role played in industrial applications. Moreover, the interaction between creep and fatigue is still not well understood and the available design tools are not effective.
Considering a topic so wide and complex, it was essential to approach and face the problems from different viewpoints strictly related one another:
-from the experimental point of view: the aim was the characterization of the high temperature fatigue behavior of different innovative materials, considering a large number of notch geometries, in order to obtain a robust experimental set of new data;
-from analytical/theoretical point of view: with the aim to develop and/or extend methods based on energy approaches to high temperature phenomena, to analyse the elastic-plastic behaviour of the material and try to give robust and reliable tool for the design against creep.
For these reasons, high temperature fatigue tests have been conducted on Cu-Co-Be alloy, 40CrMoV13.9, Titanium grade 2, and a synthesis in terms of the strain energy density of high temperature fatigue data has been proposed successfully, for the first time. In addition, on the 40CrMoV13.9 steel, an investigation on the crack initiation from notches and on the influence of surface roughness at elevated temperature was accurately conducted.
Because of the good results obtained with the SED approach, it was investigated the accuracy of the averaged SED considering a large bulk of high temperature fatigue data taken from literature. Notched components made of different C45 carbon steel at 250°C, Inconel 718 at 500°C and directionally solidified superalloy DZ125 at 850°C were considered. The control volume was derived for each material through the analytical relation within El Haddad-Smith-Topper parameter and the material characteristic length defined by the Theory of Critical Distances. SED based curves were obtained and allowed proving that the proposed approach can be a reliable design tool in practical applications when dealing with high temperature.
Relating to the creep phenomenon, the author developed a useful numerical tool allowing assessing the stress relaxation and the strain evolution against time, at the tip of blunt V-notches. In detail, starting from Neuber’s rule extended to time-dependent problems and assuming Lazzarin-Tovo equations to describe the early elastic state of the system, a set of new differential equations to be solved numerically has been derived in order to predict the evolution of stresses and strains for a material obeying a Norton power law. The results have shown an excellent prediction of the stresses and strains evolution against time, with a maximum discrepancy within theoretical and finite element method prediction of 20%. Some preliminary analyses on the extension of SED under creeping conditions have been also reported.
At the end, the contour J-Integral, developed for elastic-plastic problems, have been also considered for further applications to high temperature and creep.
The results led to several international fruitful collaborations and solid bases for interesting future development of a unified SED approach of fatigue and creepL’obiettivo del Dottorato di Ricerca era lo studio del comportamento a fatica di materiali metallici ad alta temperatura, indagando in modo particolare il fenomeno del creep, che diventa non trascurabile in determinate condizioni di carico e interagisce con la resistenza a fatica stessa. È stata ritenuta interessante soprattutto l’analisi di componenti in presenza di intagli e/o di geometrie complesse che rappresentassero in qualche modo la geometria di componenti effettivamente utilizzati nelle applicazioni industriali. Da un’iniziale e approfondita analisi bibliografica è emerso come in letteratura si trascurino la fatica ad alta temperatura ad alto numero di cicli e in particolar modo le applicazioni relative a componenti intagliati. Inoltre, l’interazione fra fatica e creep si presenta come un evento ancora poco chiaro e trattato con strumenti poco efficienti. Considerando fenomeni molto complessi e un tema così ampio, è stato indispensabile affrontare l’oggetto del presente dottorato di ricerca da diversi punti di vista ma strettamente interconnessi: -quello sperimentale: caratterizzando il comportamento a fatica ad alta temperatura di diversi materiali innovativi e multifunzionali d’interesse industriale, considerando varie geometrie d’intaglio, in modo tale da fornire un consistente numero di dati sperimentali di partenza; -quello analitico/teorico: cercando di sviluppare e/o estendere approcci energetici ad alta temperatura, analizzando il comportamento elasto-plastico, gli strumenti a disposizione e cercando, infine, di fornire strumenti efficaci per la progettazione in presenza di creep. Per queste ragioni, è stata condotta una campagna sperimentale al fine di caratterizzare il comportamento a fatica ad alta temperatura di geometrie intagliate di una lega Cu-Co-Be, 40CrMV13.9 a Titanio Grado 2. I dati sperimentali ottenuti sono stati sintetizzati in termini di Strain Energy Density, esteso per la prima volta all’alta temperatura. Sempre considerando l'acciaio 40CrMoV13.9, è stata condotta un’analisi sull’innesco di cricche a bordo foro, ad alta temperatura, valutando l’influenza della rugosità superficiale. Visti i positivi riscontri ottenuti con la sintesi in energia dei dati sperimentali, la potenzialità del metodo è stata ulteriormente verificata considerando nuovi materiali e geometrie presenti in letteratura. Sono state prese in esame prove a fatica condotte su un acciaio C45 a 250°C, Inconel 718 a 500°C e sulla superlega DZ125 a 850°C. I dati, originariamente sintetizzati attraverso la Teoria delle Distanze Critiche, sono stati ripresentati con successo in termini di densità di energia di deformazione mediata su un volume di controllo. Il raggio di controllo per ogni materiale è stato determinato attraverso la relazione che lega il raggio stesso con il parametro di El Haddad-Smith-Topper e la distanza critica caratteristica del materiale. Successivamente, il fenomeno del creep è stato accuratamente considerato. In dettaglio, è stato con successo fornito uno strumento numerico capace di prevedere il rilassamento delle tensioni e l’evoluzione delle deformazioni nel tempo, all’apice d’intagli a V raccordati. In dettaglio, partendo dall’estensione della regola di Neuber a problemi dipendenti dal tempo, e utilizzando le equazioni di Lazzarin-Tovo al fine di descrivere lo stato elastico iniziale del problema, è stato poi ricavato un set di equazioni differenziali da risolvere in modo iterativo/numerico al fine di valutare tensioni e deformazioni nel tempo, assumendo la legge di Norton per la rappresentazione del fenomeno del creep. Al fine di validare il metodo, i risultati ottenuti sono stati confrontati con quelli ricavati da accurate analisi agli elementi finiti, ottenendo un buon accordo. Tutte le tensioni sono state previste con errori trascurabili, mentre in alcuni e limitati casi, le deformazioni hanno mostrato un errore percentuale leggermente più elevato ma comunque inferiore al 20%. Sono state inoltre condotte delle analisi preliminari agli elementi finiti al fine di esplorare il comportamento del SED in presenza di creep, risultando tempo-variante ma tendente ad un valore di plateau. Infine, sono stati considerati approcci energetici alternativi utilizzati nella caratterizzazione dei fenomeni elasto-plastici che possono essere presenti alle alte temperature. In particolare, tra le varie metodologie presenti in letteratura, è stato considerato il J-Integral. L’attività lascia infine interessanti possibili sviluppi futuri di ricerca che possono portare a un approccio unificato, basato sul SED, per progettazione a fatica in presenza di creep e di forte interazione creep-fatica

Full textAbstract:
In engineering practice, mechanical components are weakened by a wide range of sharp or blunt notches and their presence has to be accurately taken into account in the design. In fact near notches a strong stress gradient is always induced when a far field loading is applied.
Aiming to investigate the integrity of notched components subjected to different loading histories, for many years to nowadays a lot of stress and strain based damage criteria have been proposed. However, in the last years, some energy based criteria have been introduced and successfully applied on notched members proving to be powerful damage prediction tools.
In particular the averaged strain energy density criterion (Lazzarin and Zambardi 2001) has been developed and used in order to assess the strength of notched components with various notch geometries subjected to different types of loading.
The aim of this work is to extend the validity of the averaged SED criterion to the three-dimensional effects arising in the vicinity of a notch and to the problems induced by the application of multiaxial static and cyclic loadings.
Taking advantage of some results obtained from multiaxial cyclic analyses, the effect of the phase displacement between the applied loads has been addressed presenting a new proposal based on the maximum tangential stress averaged over an entire loading cycle.
Finally, a dedicated software based on the cyclic plasticity theory has been developed in order to obtain the stress/strain distributions at the tip of a rounded notch subjected to uniaxial and multiaxial low cycle fatigue. A particular link between the plastic hysteresis energy at the notch tip and the averaged SED has been found representing the first potential step for a future extension of the averaged SED criterion to cyclic plasticity.Nella pratica ingegneristica, i componenti meccanici sono sovente indeboliti da discontinuità geometriche di diversa forma e dimensione, i quali devono essere tenuti in considerazione in fase di progettazione al fine di evitare malfunzionamenti o collassi strutturali. Con l’obiettivo di valutare l’integrità strutturale di componenti indeboliti da intagli soggetti a sollecitazioni di diversa natura, numerosi criteri di cedimento sono stati sviluppati considerando lo stato di tensione e/o di deformazione all’apice dell’intaglio o nelle immediate vicinanze di quest’ultimo. Inoltre, negli ultimi anni, sono stati sviluppati approcci di tipo energetico, i quali hanno dimostrato un’ottima attitudine alla previsione del cedimento di componenti intagliati. In particolare, il criterio basato sulla densità di energia di deformazione (SED) mediata all’interno di un volume strutturale è stato presentato da Lazzarin e Zambardi (2001) al fine di valutare la resistenza di componenti intagliati soggetti a diverse sollecitazioni. L’obiettivo del primo filone di ricerca di questa tesi è quello di estendere e validare il criterio SED considerando sia i modi accoppiati che si generano per effetto Poisson in componenti tridimensionali, sia problemi legati all’applicazione di sollecitazioni di modo misto e di fatica multiassiale. Prendendo spunto da alcuni risultati ottenuti nel caso di sollecitazioni cicliche, il secondo filone di ricerca ha riguardato lo studio di una proposta in grado di discriminare l’effetto dello sfasamento tra le sollecitazioni su provini intagliati a spigolo vivo soggetti a fatica multiassiale. Il terzo filone di ricerca ha riguardato l'implementazione di un software in grado di fornire le tensioni e le deformazioni elasto-plastiche all’apice di un intaglio raccordato sottoposto a fatica oligociclica. Infine, è stato possibile trovare un coefficiente di correlazione tra l'area del ciclo di isteresi all'apice dell'intaglio ed il valore della densità di energia di deformazione elasto-plastica all'interno di un volume strutturale.

Full textAbstract:
Intentionally designed or accidentally caused, notches, cracks or defects are inevitably present in engineering components and can induce high stress gradients when a far field loading is applied. Then, structural strength assessments are often based on the local stress and strain state in the close neighbourhood of the stress raisers.
The present PhD thesis is divided into six Chapters corresponding to different research topics, all related to new applications of important and widely employed local approaches to notched or cracked structural components.
In the first Chapter, the adopted local approaches, namely the Notch Stress Intensity Factor-based approach (NSIF), the averaged Strain Energy Density (SED) criterion and the Peak Stress Method (PSM), are briefly introduced and described along with their theoretical frameworks.
The second Chapter deals with brittle fracture under mixed mode static loading. A wide experimental campaign has been carried out on PMMA as well as on graphite cracked and notched specimens subjected to mixed mode I+II and I+III loading. Then, all experimental results have been reanalysed by means of the SED approach.
The third Chapter deals with multiaxial fatigue loadings. First, the fatigue strength of severely notched titanium grade 5 alloy, Ti-6Al-4V, has been investigated. Then, the SED criterion has been applied for the first time to an industrial case study, that is the multiaxial fatigue strength assessment of steel welded rollers produced by Rulmeca S.p.a. Finally, some remarks about the phase angle effect on sharp V-notched components under multiaxial fatigue have been drawn on the basis of a proposed analytical frame.
The fourth Chapter addresses the numerical study of 3D effects in notched and cracked components. Initially, the attention has been focused on coupled modes and on the effect of different boundary conditions in 3D cracked discs and plates subjected to nominal mode III or mode II loading. Then, the presence of three-dimensional effects has been investigated both theoretically and numerically in blunt notched components under cyclic plasticity conditions.
The fifth Chapter, instead, is related to the comparison between different fracture criteria. The SED approach and that based on the Finite Fracture Mechanics (FFM) have been compared considering sharp V-notches under pure mode I or mode II loading.
Finally the sixth Chapter address the link between the SED approach and the Peak Stress Method (PSM). Cracks under in-plane mixed mode I+II and out-of-plane mixed mode I+III loading have been investigated. A method to rapidly evaluate the averaged SED based on the peak stresses at the crack tip has been proposed. On the basis of the derived link, some practical applications related to the fatigue strength assessment of aluminium and steel butt welded joints and of tube-to-flange steel welded joints have been carried out.Variazioni geometriche, come intagli, cricche o difetti in generale, sono comunemente presenti nella maggior parte dei componenti meccanici e possono indurre elevati gradienti di tensione per effetto dei carichi esterni. La valutazione della resistenza strutturale dei componenti meccanici è perciò generalmente basata sullo stato di tensione e deformazione locale, nelle adiacenze di tali variazioni geometriche. La presente tesi di dottorato è divisa in sei Capitoli corrispondenti a diversi argomenti di ricerca, tutti relativi a nuove applicazioni di importanti e ampiamente diffusi approcci locali a componenti strutturali intagliati o criccati. Nel primo Capitolo, sono brevemente introdotti e descritti gli approcci locali adottati, cioè l’approccio basato sul Notch Stress Intensity Factor (NSIF), il criterio basato sulla densità di energia di deformazione mediata (SED) e il Peak Stress Method (PSM), assieme alle loro basi teorico-analitiche. Il secondo Capitolo si occupa della frattura fragile sotto carichi statici di modo misto. Una campagna sperimentale estesa è stata eseguita su provini intagliati e criccati in PMMA ed in grafite soggetti a carichi di modo misto I+II e I+III. In seguito, tutti i dati sperimentali sono stati rianalizzati per mezzo dell’approccio SED. Il terzo Capitolo tratta il tema della fatica multiassiale. Inizialmente, è stata investigata la resistenza a fatica di una lega di titanio grado 5, Ti-6Al-4V, severamente intagliata. In seguito, il criterio SED è stato applicato per la prima volta ad un caso studio di interesse industriale: la valutazione della resistenza a fatica multiassiale di rulli saldati in acciaio, prodotti da Rulmeca S.p.a. e caratterizzati da cedimenti alla radice del cordone di saldatura. Infine, prendendo in esame componenti indeboliti da intagli a V acuti soggetti a carichi di fatica multiassiale, sono state tratte alcune osservazioni sull’effetto dell’angolo di fase sulla base di un nuovo approccio analitico. Il quarto Capitolo tratta lo studio numerico e teorico degli effetti 3D in componenti intagliati e criccati. Inizialmente, l’attenzione è stata focalizzata sui modi accoppiati e sull’effetto di diverse condizioni al contorno in dischi e piastre criccate, tridimensionali e soggette ad un carico nominale di modo III o modo II. Infine la presenza di effetti 3D è stata investigata sia dal punto di vista teorico che numerico in componenti indeboliti da intagli blandi e in condizioni di plasticità ciclica. Il quinto Capitolo, invece, è relativo al confronto tra diversi criteri di cedimento. Sono stati confrontati l’approccio SED e quello basato sulla teoria della Finite Fracture Mechanics (FFM), considerando intagli a V acuti soggetti a puro modo I o puro modo II. Infine, nel sesto Capitolo è stato investigato un legame tra il criterio SED ed il Peak Stress Method (PSM). Sono stati presi in esame componenti strutturali criccati soggetti a carichi di modo misto nel piano I+II e fuori piano I+III. È stato proposto un metodo per calcolare rapidamente il SED a partire dalle tensioni di picco valutate all’apice di cricca. Il legame ottenuto tra PSM e SED è stato poi impiegato nella stima della resistenza a fatica di giunti saldati testa a testa in acciaio ed alluminio e di giunti saldati tubo-su-flangia in acciaio sottoposti a carichi torsionali.

Full textAbstract:
The present work falls within a wider framework concerning the prediction of the mechanical response of short glass fiber-reinforced thermoplastics (SFRT), which are commonly employed in the automotive industry to reduce the overall weight of the components. More in detail, the main objective of the thesis is to develop a fatigue criterion for predicting the effect of different factors affecting the fatigue strength of such materials. In this interest, the influence of the composite complex morphology (local fiber orientation and fiber content) and of notches giving rise to stress concentrations is taken into account. In the present thesis, an experimental activity related to plain and notched specimens is firstly presented. In this context, data resulting from computed tomography (CT) analyses are shown. The latter serve to evaluate the specimens’ fiber orientation distributions, which are quantified by means of fiber orientation tensors (FOT). Furthermore, fatigue test data on the considered coupons, in the absence and in the presence of notches (with radii of 0.1 mm, 0.2 mm, 2 mm and 5 mm), are presented for different fiber orientations and weight fractions (15 wt%, 25 wt%, 35 wt% and 50 wt%). Secondly, being aware of the fact that the onset of a macroscopic crack is driven by the evolution of damage at the matrix level, a multiscale fatigue model relying on matrix stress distributions is presented. The calculation of the matrix stress cumulative distribution functions is achieved by formulating an analytical numerical pseudo-grain approach (i) permitting to avoid the generation, mesh and solution of complex microstructures, but only relying on the solution of simple unidirectional cells. The pseudo-grain method is subsequently included in the formulation of a fatigue criterion, for plain (ii), at first, and for notched specimens (iii), subsequently. The proposed fatigue criterion is eventually validated with a bulk of experimental data, partially presented in this work. Namely, fiber orientation tensors are used to properly assign the anisotropic elastic properties to the developed numerical models and the presented fatigue data are employed to assess the efficacy of the model in terms of fatigue strength prediction.Questa tesi di dottorato di ricerca si inserisce all’interno di un quadro più ampio relativo alla previsione del comportamento meccanico di materie termoplastiche rinforzate con fibre corte di vetro. Tali materiali compositi sono spesso impiegati nell’industria automobilistica per ridurre il peso complessivo della componentistica coinvolta. L’obbiettivo principale di questo lavoro è legato alla necessità di sviluppare criteri di cedimento che prevedano l’influenza di diversi fattori sulla resistenza a fatica di tali materiali. In particolar modo, si è scelto di focalizzarsi sull’effetto della morfologia (orientazione locale e contenuto di fibre) e della presenza di intagli, che a loro volta danno luogo a concentrazioni tensionali. In questa tesi viene presentata innanzitutto l’attività sperimentale svolta. Ovvero si riportano dati relativi ad analisi ottenute tramite tomografia computerizzata (CT). Quest’ultima ha il ruolo di fornire informazioni sulle distribuzioni locali dell’orientazione delle fibre, le quali vengono quantificate tramite il tensore di orientazione delle fibre (FOT). Inoltre, si presentano dati relativi al comportamento a fatica di provini con e senza intagli (di raggio pari a 0.1 mm, 0.2 mm, 2 mm e 5 mm), considerando contemporaneamente l’effetto dell’orientazione delle fibre e delle loro frazioni di peso (15 wt%, 25 wt%, 35 wt% e 50 wt%). In secondo luogo, consapevoli del fatto che l’origine di cricche macroscopiche può essere imputata all’evoluzione del danneggiamento nella matrice, si propone un modello multiscala per la previsione della vita a fatica di tali compositi, basandosi sul calcolo delle distribuzioni tensionali locali. Il calcolo delle funzioni cumulate delle tensioni matriciali è ottenuto tramite la formulazione di un approccio analitico-numerico di tipo pseudo-grain (i). Quest’ultimo permette quindi di evitare la generazione, mesh e risoluzione di microstrutture complesse e di ottenere i risultati desiderati tramite semplici modelli numerici unidirezionali. Tale approccio viene poi inserito nella formulazione di un criterio di fatica per provini lisci (ii) e intagliati (iii). Il criterio proposto è poi validato con un numero consistente di dati sperimentali, parte dei quali è presentata in questo lavoro. In particolare, i tensori di orientazione delle fibre sono impiegati per assegnare le proprietà elastiche anisotrope ai modelli numerici. I dati di fatica sono invece utilizzati per verificare l’efficacia del modello in termini di previsione della resistenza a fatica di provini lisci e intagliati.

Full textAbstract:
The study aims at tackling a problem of use of engraved gems for self-presentation and propaganda purposes in the Roman Republic and under Augustus. The most important observation about the gems in this dissertation is that they portray Roman society at each level. They are snapshots of people believes, ideologies, everyday life and thus, they might cast some light at propaganda actions performed by Roman political leaders and their factions in the past. Gems are plausible to show both, general trends in propaganda activities as well as individual and private acts of being involved in politics, since they were objects of strictly personal use. They enable us to analyse and learn Roman propaganda from a completely different angle than coins, sculpture or literature. The miniaturism of ancient gems is often in inverse proportion to their cultural significance. Despite - or perhaps because of - their ubiquity, the motifs they bear are often highly sophisticated and captivating in their visual presentation of complex ideas. By such effective artistry the image is, almost literally, impressed upon the mind of the viewer. However, it is not easy to spot and correctly interpret propaganda messages encoded on gems. In contrary, the richness of iconography and forms often leads to overinterpretations. Therefore, the point of departure here is a database covering a wide range of information categories, which have guided the structure of the presentation. It is a combination of numerous case studies of 'propaganda gems' and a critical study of the previous scholarship, which tended to use the term propaganda for representations not necessarily related to this matter. The idea is not only to present clear-cut examples of 'propaganda gems', but also to discuss those problematical pieces and issues related to them. Hence, the aim is to offer a more complete analysis of the problem previously neglected. The study is organised into five main parts. First goes introduction outlining state of research on the subject of use of gems for self-presentation and propaganda purposes as well as aims of the dissertation, methodology employed and structure of the thesis. The second part includes definitions and characteristics of propaganda phenomenon as a term circulating in the current studies of semiotics and communication. It discusses various forms of propaganda, its basic tools and techniques as well as hypothesies about their effectiveness if applied in the studies of ancient society. It also draws attention to some problems related to ancient (e.g. Roman) propaganda studies. The third part discusses an evolutionary model of use of engraved gems from self-presentation to propaganda purposes in the Roman Republic and under Augustus. It is clear that propaganda on intaglios and cameos stems from the phenomenon of self-presentation. Apart from utilitarian motivations like sealing, it was the need and desire to present and express oneself in a specific, usually improved and bringing positive associations way, that was one of the key-impulses for production of gems in the 3rd century BC ancient Rome. That phenomenon is typical for Etruscan, Italic, Roman and Hellenistic cultural elements that have been merging over two centuries into one Graeco-Roman glyptic tradition. First presentations of Roman victorious generals on gems combined with commemoration of important political events and most importantly boost of personal branding through portraits engraved upon precious and semi-precious stones resulted in a transformation into a complex machinery involving manifestation of loyalty to the patron and affiliation to the faction, promotion of family members and application of divine and heroic natures into the self-image. One observes first tentative attempts of use of gems for propaganda purposes already in the 3rd and 2nd century BC, while there is a clear start of a fully aware propagandistic actions reflected in glyptic material in the early 1st century BC (Sulla's dictatorship). The later fierce rivalry between Pompey the Great, who is traditionally assigned to popularise use of gems in ancient Rome, and Julius Caesar shows that glyptic art has been gradually incorporated to the propaganda machinery of Roman political leaders. The peak of production what one might call 'propaganda gems' is witnessed after death of Caesar in 44 BC and endures until the Actium battle in 31 BC. Then, gems like every other category of Roman art and craftsmanship became a part of a sophisticated language greatly influenced by Imperial rhetoric and ideology carefully designed by Augustus. The fourth part describes the context of 'propaganda gems' in the Roman Republic and under Augustus. The chapters included here contain remarks on the production, distribution, usage and cultural significance of gems. The base is information extracted from ancient literary sources which are followed by archaeological observations of the material considered here as related to self-presentation and propaganda matters and presented in the second part of the dissertation. More theoretical considerations about propagandistic value of engraved gems and possible target groups using them are offered here as well. To show the dynamics of using gems for propaganda purposes a separate chapter has been created that includes statistical analyses of either the whole phenomenon as well as individual categories like portrait gems, those presenting divine and mythological references and so on. Finally, the last chapter presents conclusions and it is also designed to present potential similarities and differences between gems and other artistic media, notably coins, in respect of propaganda. The last, fifth part of the study comprises of a catalogue, bibliography, list of figures, tables, charts, maps and plates. The specific characteristics of engraved gems, their strictly private character and the whole array of devices appearing on them are examined here in respect to their potential propagandistic value. This analysis is performed in the wider scope providing first comprehensive picture covering many aspects of Roman propaganda and a critical survey of overinterpretations of this term in regard to the glyptic art. The ultimate achievement is incorporation of this class of archaeological artefacts into the well-established studies of Roman propaganda as well as the Roman society in general. Gems turn out to be not only another media used by propagandists but also a very sensitive barometer of social moods. It remains disputable to what extent they were helpful in creation of propaganda communications by Roman political leaders, but it is clear that their role in evolution of Roman propaganda should be taken into account in the further studies of this phenomenon.

Due to the development of science technology, the digital duplicating technology such as color copiers, color scanning had been progressed fast accordingly, and caused the counterfeit of securities more easy. Followed seriously impact the safety of security documents. The printed image of Intaglio printing showed sharpness line, thickly film, multi-layer tone and with unique three-dimension tactility. Not only the digital duplicating technology were unable to duplicate it, but also difficult to counterfeite even with other printing method. Thus, so far, Intaglio printing is the backbone of banknotes and securities.According to Hans (2002) reported, the steps of recognition on banknotes for pubic people is first to “feel” the intaglio tactile image with finger, and then “look” watermark and security thread with eyes. Therefore, the tactile images of intaglio printing is an important security feature. So, how to strengthen to tactility of intaglio printing, in order to improve the anti-counterfeit function of securities, is an important subject that is worth probing into. Thus, the purpose of this study is to explore embossing effect which affect the tactility of printed images. This study used two factors experimental design, one is for paper stiffness, the other for engraving breadth. The result of the study indicated as follow :1.The stiffness is in inverse proportion to embossing height, in other words that will receive lower embossing height while using higher stiffness to print. 2.The engraving breadth is in direct proportion to embossing height, , that is to say when is the larger the engraving breadth , the higher the embossing height received is.3.The stiffness and breadth to highly having interaction, in another word that will change the embossing height while changing the stiffness, meanwhile, while changing the breadth, the height will be influenced too.

Full textAbstract:
This dissertation reveals significant aspects of the use and understanding of prints in seventeenth-century Sicily by exploring their function in the realm of sacred images. It centers on three of the most substantial printmaking ventures carried out in Palermo and Messina: Ottavio Gaetani's Icons of Mary (Palermo, 1663), Placido Samperi's Iconology of the Virgin (Messina, 1644), and Giordano Cascini's St. Rosalia (Palermo, 1651). All three books treat religious subjects and feature intaglio prints claiming to reproduce the sacred images – paintings, sculptures, and mosaics – that constitute a crucial element of each narrative. The project examines the production of these works and the subsequent textual and visual responses made on the island and at farther distances. The three chapters treat each book both as a collection of prints and as an exchange between text and image that renders those prints as evidence for the value and flexibility of images.
The first chapter focuses on Gaetani’s collection of icons of the Virgin from through the island and the utilization of prints as effective surrogates for those miraculous images. In the second chapter, the lines between devotional and art historical value are questioned in Samperi’s illustrated collection of paintings and sculptures depicting the Virgin. The third chapter unfolds the strategies by which prints were presented as evidence of a cult’s material history and continued to inform St. Rosalia’s legitimacy. In doing so, the chapters reveal a range of possible understandings of the relationship between prints and their sources, as well as active manipulations of that relationship to a range of ends. The dissertation identifies a Sicilian approach to generating historical, political, and sacred narratives that was inventive in both depending on and incorporating the reproduction of images in print.

This report outlines the conceptual, procedural and formal descriptions of the artistic development I have acquired over the course of the past three years. The current violent events caused by the War on Drugs in México –my home country- led me to this research. Beginning with the idea of erasure as language, I concentrated on the use of processes that are reductive in nature to create the bodies of work mentioned in this report.
Thousands of people die in drug-related violence every year in México; by using metaphors and visual metonymies to tie together process and subject matter I explore the idea of perception, memory and transformation. I believe my work is derived from a need to find meaning in these brutal events that repositions the corpse in our field of vision, reminding us that our physical existence is finite.text
