Introduction. The partial replacement of cast-in-situ concrete with precast concrete in the residential construction sector allows to reduce construction time and cost, increase labour productivity and cut CO2 emissions. Combinations of prefabricated and monolithic elements in precast monolithic frames are presented; they encompass 6 different structural options of precast monolithic frames and 2 types of monolithic frames. The co-authors compare production costs and integrated labor intensity for all frame design options, construction periods per 1,000 m3 of a residential building for various structural options of the frame, and assess potential reduction in carbon dioxide emissions due to a change in the amount of precast reinforced concrete in the building frame structure.
 Materials and methods. The co-authors have developed a method that employs weighted average to identify the optimal type of a precast monolithic frame. The method takes account of such factors as production costs, integrated labour intensity, construction time and reduction in carbon dioxide gas emissions (in per centum) per 1,000 m3 of the frame structure.
 Results. The optimal structure of a precast monolithic frame was selected and calculated using weighted average. Weighted average was used to identify the most effective structural frame. The calculation results have shown that ARKOS precast monolithic frame with precast columns is the leader in terms of weighted average; it best suits the construction of a residential building. If we consider each of the selected indicators separately, RECON frame with precast floors is to be selected; however, RECON is inferior to ARKOS in terms of weighted average due to different values of the weight coefficients attached to each of the assessment criteria.
 Conclusions. The co-authors have proven the efficiency of precast monolithic frame systems in comparison with monolithic frames if applied to construct a residential building. The proposed method was employed to select the optimal type of frame.

Full textAbstract:
The paper considers the question of substantiating the choice of criteria for limiting states of monolithic reinforced concrete bearing systems for the regime of progressive collapse. Based on the results of computational and theoretical studies, structural elements and structural units of monolithic reinforced concrete buildings are determined, the destruction of which occurs first of all in the event of a failure of the vertical bearing structure. It is established that the destruction of such structural units and structural elements leads to the initialization of the process of progressive collapse. A computational and theoretical analysis has been performed to determine the ultimate deformation effects or load values according to the criteria for the bearing capacity of crutial units of monolithic reinforced concrete systems with different span sizes. It is established that as a basic criterion for estimating the stress-and-strain state of monolithic reinforced concrete structures for the mode of failure of a vertical bearing structure, the relative deformation amount corresponding to the formation of the “fracture” zone of the retaining section of the overlap under the action of transverse forces can be adopted.

The paper presents a method of using the reduction factor to ensure the stability of monolithic reinforced concrete bearing structures to progressive collapse. Within the framework of the verification study, the correctness and validity of the developed method for the computational analysis of monolithic reinforced concrete bearing systems of buildings and structures to resist progressive collapse were proved. The reduction factor (K1) obtained and justified in the framework of the research performed is the most important deformation characteristic of the special limiting state of monolithic reinforced concrete bearing systems of buildings and structures for an emergency design situation associated with the failure of a local structural element.

Abstract: Dome is an element similar to the hollow half of a sphere. It can also be defined as a thin shell generated by the revolution of a regular curve about one of its axes. The type of the curve and the direction of the axis of revolution determines the shape of the dome. Monolithic dome structures are cast in a one-piece form. The paper aims to do a comprehensive study of Monolithic Domes and the various advantages and key aspects of these structures and to determine whether they are more energy efficient, eco-friendly, cost effective and durable housing options compared to conventional structural systems. Keywords: Low Cost Housing, Monolithic Domes, Cylindrical Structures, Structural analysis, paper review

With the help of probabilistic modeling, the issues related to the assessment of the robustness of structural systems made of prefabricated and monolithic reinforced concrete in an accidental design situation are considered. The paper considers the concept of analyzing the reliability of structural systems and differentiating risks in accidental design situations. The existing probabilistic models of the basic variables included in the functions of loads and resistances are analyzed. Statistical parameters of the uncertainty of the resistance model are obtained and integrated in the form of a basic variable with probability modeling. Probabilistic modeling of structural systems made of precast and monolithic reinforced concrete, designed according to the current standards of the Republic of Belarus, was carried out using the Monte Carlo method. The functions of the limiting state of the structural system in an accidental design situation with the sudden removal of the central column of the first floor are determined. As a result, values of failure probabilities and corresponding reliability indices were obtained for the considered constructive systems.

Full textAbstract:
Recently, interest in using precast concrete (PC) modules has increased due to their better seismic performance than steel modules. However, they must be joined by additional elements to ensure structural integration between the modules. The essential aim of the precast concrete module is to ensure structural performance with appropriate connection methods. However, the technical problem of connecting PC modules still needs to be improved. This study proposed a PC modular beam system for improved structural and splicing performance, and simple construction. This modular system consisted of modules with steel plates inserted to improve integrity of modules, ease of construction, and low cost. The structural performance of the proposed PC modular beam system was evaluated by flexural test on one reinforced concrete (RC) beam specimen consisting of a monolithic beam, and two PC specimens with the proposed modular system. The results demonstrated that the proposed PC modular beam system achieved approximately 80% of the structural performance compared to the monolithic specimen, with approximately 1.3-fold greater ductility.

Prefabricated monolithic frame systems have the best indicators for the consumption of concrete and reinforcement per square meter of the total area of the building compared to the monolithic frames being massively erected today. Economic efficiency is achieved through the use of factory-made prestressed reinforced concrete elements in a prefabricated monolithic frame. Currently, new technologies for the production of structures by the method of formless molding on long stands are rapidly replacing the traditional method of manufacturing prestressed products by the aggregate-flow method. When developing structural solutions of the prefabricated monolithic frame system «MKS», the possibilities of the technology of continuous formless molding of reinforced concrete products were used, in which the device of cutouts, holes, recesses for dowels, loop releases, releases of prestressed reinforcement at the ends of the elements, the addition of indirect reinforcement grids in the area of the lower prestressed reinforcement is provided. All structural components and individual elements in the «MKS» system can be designed on the basis of existing regulatory documents. However, some regulatory documents, according to which the design of prefabricated monolithic structures is carried out, are either advisory in nature or outdated. Some modern methods of calculating the nodes of the prefabricated monolithic frame «MKS» are not reflected in regulatory documents, which constrains the mass application of both the «MKS» system and the prefabricated monolithic housing construction as a whole.

Full textAbstract:
Due to the increasing types of special impacts on buildings and structures, which often have a dynamic nature, there is a need to improve structural systems to ensure protection against such impacts. Reducing the weight of load-bearing structures of building frames and increasing the static indeterminacy of structural systems are among the effective methods of protection not only under seismic conditions but also during special and emergency impacts. As part of addressing this issue, the article proposes a new rapidly erectable structural system for residential and public buildings, made from industrialized panel-frame elements in a precast-monolithic configuration. In this system, the building frame is assembled from precast reinforced concrete structures of two types: panel-frames in the form of inverted U-shaped elements and L-shaped industrially manufactured elements. The connection of these structures on the construction site into the building frame, within the plane of the panel-frames, is carried out using two types of platform joints and monolithic embedding of the upper parts of the precast panel-frame elements’ beams together with multi-void slabs. In the orthogonal plane of the panel-frames, the frame is formed by monolithic tie beams and multi-void floor slabs. The conducted assessment of the mechanical safety of the proposed structural system demonstrated its high resistance to progressive collapse under special impacts. A comparative analysis of technical and economic indicators, such as material consumption, cost, and transportation expenses, revealed significant advantages over buildings constructed using traditional panel systems.

Full textAbstract:
The article presents ways of selecting effective designs and technological and organizational solutions for the bonded thermal insulation systems of complex-shaped facades based on thermal field and flow modeling using the SolidWorks Simulation Xpress 2021 software and experimental–statistical modeling using the Compex program. Determining optimal insulation parameters at the design stage will help eliminate the negative effects of thermal bridges at balcony junctions and reduce the cost of implementing bonded thermal insulation systems for facades with complex shapes. It has been established that the most effective approach is to insulate not the entire perimeter of the balcony slab, as required by normative documentation, but rather to insulate a sufficient portion of the exterior wall, which is equal to 750 mm, with a 30 mm insulation thickness on top of the slab and 50 mm beneath it. This insulation technology is economically feasible for modern multistory buildings with nonstandard volumetric and architectural solutions, constructed using frame–brick, frame–monolithic, or monolithic schemes without thermal breaks between the balcony slab and the monolithic floor slab, with open-type balconies, bays, or uncovered loggias.

Le travail de cette thèse a pour objectif de développer un solveur dédié aux problèmes d'interaction fluide-structure (IFS), en particulier ceux rencontré en biologie, tels que la dynamique d'un écoulement sanguin à travers des tronçons veineux munis de valves. La circulation du sang est étudiée à l'aide de modèles pertinents sur les plans anatomique et physique. Le premier aspect des problèmes d'IFS concerne la gestion de la stabilité. Une formulation monolithique eulérienne basée sur la méthode des caractéristiques assure la stabilité inconditionnelle et introduit une approximation du premier ordre en temps avec deux modèles distincts de matériaux hyper élastiques. Le second aspect est relatif au contact entre deux parties du domaine solide, tel celui apparaissant entre deux valvules au cours de la fermeture de la valve et à l'état fermé sur un surface valvulaire relativement importante. Un algorithme de contact est proposé et validé à l'aide de tests de référence. L'étude computationnelle de l'écoulement sanguin à travers des tronçons veineux munis de valves est mené, une fois le solveur IFS vérifié et validé. Le domaine computationnel bidimensionnel est soit constitué d'une simple unité de base, soit du modèle de circuit veineux en forme d'échelle avec une veine superficielle et une profonde, communicant par une série de veines perforantes. Un maillage tridimensionnel de l'unité de base a été construit. Les simulations dans ce domaine tridimensionnel nécessite le recours au calcul haute performance. La dynamique de l'écoulement sanguin est fortement couplée à la mécanique de la paroi vasculaire. La paroi déformable des veines et artères de gros calibre est composée de trois couches principales (l'intima, la media, et l'adventitia) constituées de matériaux composites ayant une composition spécifique dans chaque couche. Dans ce travail, la rhéologie de la paroi est supposée être représentée par un matériau du type Mooney-Rivlin<br>The present work aims at developing a numerical solver for fluid-structure interaction (FSI) problems, especially those encountered in biology such as blood circulation in valved veins. Blood flow is investigated using anatomically and physically relevant models. The first aspect of FSI problems is related to management of algorithm stability. An Eulerian monolithic formulation based on the characteristic method unconditionally achieves stability and introduce a first order in time approximation with two distinct hyperelastic material models. The second aspect deals with between-solid domain contact such as that between valve leaflets during closure and in the closed state over a finite surface, which avoid vcusp tilting and back flow. A contact algorithm is proposed and validated using benchmarks. Computational study of blood flow in valved veins is investigated, once the solver was verified and validated. The 2D computational domain comprises a single basic unit or the ladder-like model of a deep and superficial veins communicating by a set of perforating veins. A 3D mesh of the basic unit was also built. Three-dimensional computation relies on high performance computing. Blood flow dynamics is strongly coupled to vessel wall mechanics. Deformable vascular walls of large veins and arteries are composed of three main layers (intima, media, and adventitia) that consist of composite material with a composition specific to each layer. In the present work, the wall rheology is assumed to be a Mooney-Rivlin material

The way the structure of systems and programs are designed is very important. When working with smaller groups of systems, the chosen architecture does not affect the performance and efficiency greatly, but as these systems increase in size and complexity, the choice of architecture becomes a very important one. Problems that can arise when the complexity of software scales up are waiting for data accesses, long sequential executions and potential loss of data. There is no single, optimal software architecture, as there are countless different ways to design programs, but it is interesting to look at which architectures perform the best in terms of execution time when handling multiple bigger systems and large amounts of data. In this thesis, a case called "The Income Deduction" will be implemented in a monolithic and an event-driven architectural style and then be put through three different scenarios. The monolithic architecture was chosen due to its simplicity and popularity when constructing simpler programs and systems, while the event-driven architecture was chosen due to its theoretical benefits of removing sequential communicating between systems and thus reduce the time systems spend waiting for each other to respond. The main research question to answer is what the main benefits and drawbacks are when building larger systems with an event-driven architectural style. Additional research questions include how the architecture affects the organisation’s efficiency and cooperation between different teams, as well as how the security of data is handled. The two implementations where put through three different scenarios within the case, measuring execution time, number of HTTP requests sent, database accesses and events emitted. The results show that the event-driven architecture performed 9.4% slower in the first scenario and 0.5% slower in the second scenario. In the third scenario the event-driven architecture performed 49.0% faster than the monolithic implementation, finishing the scenario in less than half the amount of time. The monolithic implementation generally performed well in the simpler scenarios 1 and 2, where the systems had fewer integrations to each other. In these cases it is the preferred solution since it is easier to design and implement. The event-driven solution did perform much better in the more complex scenario 3, where a lot of systems and integrations were involved, since it could remove certain connections between systems. Lastly, this thesis also discusses the sustainability and ethics of the study, as well as the limitations of the research and potential future work.<br>Strukturen som system och program designas efter är väldigt viktigt. När en arbetar med mindre grupper av system så kommer den valda arkitekturen inte att påverka prestandan mycket. Men när dessa system växter i storlek och komplexitet så kommer valet av arkitektur vara väldigt viktigt. Problem som kan uppstå när mjukvarukomplexiteten ökar är väntandet på dataaccesser, långa sekventiella exekveringar och potentiell förlust av data. Det finns ingen optimal mjukvaruarkitektur, det finns oräkneligt många sätt att designa program. Det är intressant att kolla på vilka arkitekturer som preseterar bäst sätt till exekveringstid när en hanterar ett flertal större system och stora mängder data. I den här avhandlingen kommer ett fall, kallat "Ingångsavdraget", att implementeras i en monolitisk och en event-driven arkitekturell stil och sedan köras igenom tre olika scenarion. Den monolitiska arkitekturen var vald på grund av dess enkelhet och populäritet vid utveckling av enklar program och system. Den event-drivna arkitekturen valdes på grund av vissa teoretiska fördelar, så som att kunna undvika sekventiell kommunikation mellan systemen och därmed reducera tiden som systemen väntar på svar från varandra. Den huvudsakliga forskningsfrågan som ska besvaras är vad de största fördelarna och nackdelarna är när man bygger större system med en event-driven arkitekturell stil. Andra forskningsfrågor inkludera hur arkitekturen påverkar effektiviteten hos en organisation och samarbetet mellan olika team, samt hur datasäkerheten hanteras. De två implementationerna sattes igång tre olika scenarion inom fallet, där exekveringstid, antal HTTP-anrop skickade, databasaccesser och event skickad mättes. Resultaten visar att den event-drivna arkitekturen presterade 9.4% långsamare i det första scenariot och 0.5% långsamare i det andra scenariot. I det tredje scenariot presterade den event-drivna lösningen 49.0% snabbare än den monolitiska lösningen och avslutade därmed scenariot under hälften av tiden. Den monolitiska implementationen presterade generellt väl under de simplare scenarion 1 och 2, där systemen hade färre integrationer till varandra. I dessa fallen så är den den föredragna lösningen eftersom det är lättare att designa och implementera. Den event-drivna lösningen presterade mycket bättre i det mer komplexa scenario 3, där många system och integrationer var inblandade, eftersom den kunde ta bort vissa kopplingar mellan system. Slutligen så diskuteras även hållbarhet och etik i studien, samt begränsningarna av forskningen och potentiellt framtida arbete.

Full textAbstract:
Romanticized notions of how one becomes an “artist” have long been questioned, so why do we still fetishize them in popular culture, turning a blind eye to the politics of exclusionism that characterize the art world and conforming our creative potential to well-trodden stereotypes? I'm Not an Artistis a critical appraisal of the role of the artist through time and an account of how successful artists have conquered their spot in the history of art, from the rise of the Renaissance artist star to the multiplicity of artistic identities we see in the creative landscape today. Entertaining, informative, and packed with important but lesser-known stories about how artists became famous, it examines the cultural importance of the professional label “artist” and invites readers to “give up the artist myth” in order to rediscover creativity beyond the stronghold of institutions, markets, trends, and cultural clichés. It’s a book about art, artists, art history, and the art market as well as the role creativity plays in our lives and how outdated power structures and professional labels are a hindrance to unlocking creative potential. Openly engaging with the contradictions and paradoxes that currently define the relationship between artists, the education system, and the art market, the book proposes an eco-cultural model that can allow artists to reconfigure their identities, and in the process tilt the artworld’s axis. By turns a critical framework for examining what constitutes the term “artist”, an alternative art historical account and a no holds barred guide to how the art world really works, this boundary-breaking book challenges existing practices, methodologies, and metrics of success, calling for a fairer art world that is non-elitist and multicultural. It allows readers to critically position themselves in today’s art world in a clear, ethically grounded, and responsible way. Let’s imagine a world without artists. The romantic artist myth belongs to the category of colonial heroes we no longer need, so why do we still fetishize it in popular culture and let its stereotypes define our creative potential? I’m Not an Artist examines the cultural importance of the professional label “artist”, the history of its myth, and its influence across time to critically address the complications it brings to the creative panorama of our time. This is a book about art, artists, art history, and the art market as well as the role creativity plays in our lives and how our creative potential is hindered when we trap ourselves in outdated power structures and outdated professional labels. Written for art students, art lovers, and artists whose careers have not yet begun or are not going as planned, this book focuses on how artists truly became successful by carefully negotiating, masterminding, and orchestrating their success. The word artist is a ruin, a crumbling monolith stuck in the past. What shall we do with it? I’m Not an Artist proposes an ecological model that invites us to overcome the entrapments of the artist myth and rediscover creativity beyond the stronghold of institutions, markets, trends, and cultural clichés.

This is because these components have excellent material properties for lightweight applications, such as a high strength-to-weight ratio and good corrosion resistance [2]. A typical manufacturing process to produce such structural components is milling. For these weight-optimized, monolithic components, up to 95% of the material is removed by machining [3]. The challenge with these thin-walled structural components, which are up to 14 m long, is that part distortion can occur because of the manufacturing-specific process chain [4]. Residual stresses due to machining and upstream processes such as forming, and heat-treatments are known to be the key factor for causing those distortions [5].In this research the effect of the residual stresses, the machining strategy, the part topology and the geometry, including the wall-thickness, on distortion were investigated experimentally, and simulatively by validated virtual models based on the finite-element method. Those models can then be used to predict the distortion. At the end distortion minimization techniques were derived.

AbstractRobotic drilling systems have been used in the manufacture of large aerospace components for a number of years. Systems have been developed by several systems integrators in order to accurately drill materials from CFRP to Titanium. These systems, however, have been unable to achieve large diameter holes in Titanium due to reduced structural stiffness and end effector capabilities. Typically, large holes are either drilled using large cartesian CNC-controlled machines or drilled using automated drilling units (ADU). However, there is a pull from aerospace OEMS to move away from large monolithic machines, in favour of flexible robotic system. Flexible robotic systems provide a number of benefits for large structure assembly. The following report primarily outlines drilling trials conducted on the Accurate Robotic Machining System, during which holes from 25 mm to 32 mm ID were drilled in titanium implementing an empirical test schedule. Additionally, a discussion on the benefits of drilling large diameter holes using flexible robotic platforms.

AbstractThe global aerospace industry is driving a demand for flexible manufacturing systems to accommodate multiple programs with variable capacities within a modular, economical production cell [1]. Traditional manufacturing cells often involve bespoke, monolithic hardware limited to single program use. This inherent restraint results in significant incurred costs and program disruption when reacting to design and capacity changes. This paper describes the development of a reconfigurable panel-indexing cell with a dynamic cost architecture as an alternative approach to established, monolithic tooling structures.

AbstractSoftware-defined Manufacturing (SDM) aims to enhance the flexibility of production systems. Classical automation systems are not a suitable technological basis for SDM. While their hierarchical, rigid structures are increasingly being dissolved. Container-based virtualization, and modular software architectures, gain traction in automation systems. However, today’s PLCs are not a perfect fit for virtualization, as the control program still is a monolithic piece of software. We analyze cyclic and event-based real-time scheduling models for modular PLCs. Furthermore, techniques for reconfiguration at runtime are developed based on the selected execution models.

AbstractIn general, current systems for the Digital Factory implement a product-process-resource (PPR) data model in a monolithic rich-client/server architecture with a single database persistence layer. Common data objects are the product bills of material, descriptions of the production processes, or the resource structure, e.g. bill of equipment. The main drawback of the current monolithic architecture is the slow rate of development, which prevents fast adoption of the software to the new production planning process (i.e., due to new technologies for the transformation of the automotive industry with the goal of electrification) is not possible. Furthermore, time-consuming and error-prone export-import operations characterize the collaboration of the engineering supply chain. Mercedes-Benz has created a new IT system architecture for their Digital Factory. The core idea of this architecture is a module-based approach. Each planning step has its own module, e.g. product analysis, layout planning or cost calculation. One single module consists of a server-based business logic, a web-based user interface and its own database. Each module is the source of master data objects that originate from the corresponding planning step and refers to data objects from predecessor planning steps. The single modules communicate mostly via KAFKA. The usage of a model based application engine allows the fast creation of different modules. Best-of-breed third-party systems for specific planning steps can be integrated into the system architecture. Web technologies allow suppliers to access the Mercedes-Benz systems directly for a fully integrated supplier collaboration. Roll-out has started and has already led to significant efficiencies.

Full textAbstract:
The widespread approach for Multi-Disciplinary Optimization (MDO) problems adopted in the Space industry generally follows a sequential logic by neglecting the interconnection among different disciplines. However, since the optimization objectives in the different fields are often conflicting, this methodology can fail to find global optimal solutions. By restricting the analysis to just structure and control fields, the common hierarchy is to preliminary define the structure by optimizing the physical design parameters and then leave the floor to the control optimization. This process can be iterated several times before a converging solution is found and control performance is met. Especially for large flexible structures, the minimization of the structural mass corresponds in fact to an increase in spacecraft flexibility, by bringing natural modes to lower frequencies where the interaction with the Attitude Control System (ACS) can be critical, especially in the presence of system uncertainties. Modern MDO techniques nowadays represents a tool to enhance the optimization task by integrating in a unique process all the objectives and constraints coming from each field. Two kinds of architectures can be distinguished in the MDO framework: monolithic and distributed. In a monolithic approach, a single optimization problem is solved, while in a distributed architecture the same problem is partitioned into multiple sub-problems containing smaller subsets of the variables and constraints. The development in the last decade of structured H∞ control synthesis opened the possibility of robust optimal co-design of structured controllers and tunable physical parameters. In fact, Linear Fractional Transform (LFT) formalism allows one to embed in the dynamic model tunable physical parameters treated as parametric uncertainties. In addition, thanks to these techniques, particular properties can be imposed on the controller, such as internal stability or performance respecting a frequency template, in the face of all the parametric uncertainties of the plant. This point is particularly important for aerospace applications where requirements are generally challenging and structural uncertainty, coming for example from an imperfect manufacturing or assembly, cannot be neglected. It has to be said that these techniques do not guarantee a global optimal solution of problem, so a good first guess can enhance the quality of the result. Alazard et al. [1] demonstrated how this multi-model methodology implemented in H∞ framework can be enlarged to include integrated design between certain tunable parameters of the controlled system and the stabilizing structured controller. There exist as well in literature a large class of problems where coupling between structure and control is considered unidirectional. This means that the objective function of the structural sub-problem depends only on the structural design parameters while the control criterion depends on both structural and control design parameters. A partition of the structure and controller design variables is desirable for practical implementation when the impact of the controller variables on the structural objective is relatively small. A strategy in this case is to solve the system-level problem as a nested optimization one, as in the BIOMASS test case [2]. For the present study both monolithic and distributed architectures are investigated on a real benchmark, the ENVISION spacecraft preliminary design. In particular, the problem formulation in the multi-body Two-Input Two-Output Ports (TITOP) [3] modelling approach allows the author to easily define an MDO problem by including all possible system uncertainties from the very beginning of the spacecraft design. In this way not only a structure/control co-design is possible, but system performance is robustly guaranteed. Where an analytical model of the structure is sufficient to describe the various spacecraft sub-components, a dependency from the design parameters can be captured in a minimal LFT model (built in SDTlib). In this approach the control/structure co-design problem is solved in a unique iteration by using the non-smooth techniques available in the Robust Control community. When the complexity of a structure cannot be handled with a simple analytical model (i.e. finer Finite Element Model (FEM) are necessary to ensure representativeness), a distributed architecture will be preferred. A nested optimization process is in fact necessary when a FEM software such as NASTRAN has to be interfaced with the control synthesis/analysis tools available within MATLAB/SIMULINK. In this case, the strategy is to iteratively optimize an inner H∞ control problem, which depends on both control and structural design variables, and the structural design themselves tare optimized by an outer global optimization routine. The aim of this paper is finally to contribute to the evolution of industrial practice in control/structure co-design, by proposing a unified and generic approach based on a well-posed modelling problem that integrates both design parameters and parametric uncertainties in a unique representation. The advantage offered by this framework is dual: to shortcut the unnecessary iterations among different fields of expertise and to speed up the validation and verification process by directly producing a robust preliminary design.

This research introduces an integrated vibration energy harvester and electrochemical energy storage device that can effectively convert ambient vibrations directly into stored electrochemical energy. The electrochemical energy storage device is an electrical double layer capacitor (EDLC) with an ionic redox transistor as its membrane separator. This ‘smart’ membrane separator directly rectifies the electrical energy generated by the transduction from the nonlinear energy harvester, creating an ionic polarization across the membrane separator for storage. This electrochemical gradient can be subsequently used for powering sensor electronics as required in various applications, including structural condition monitoring. The alternating voltage developed by the energy harvester (+/−5V around 100 Hz) is connected to an aqueous supercapacitor fabricated from nanofibrous carbon paper electrodes and a polypyrrole-based (PPy(DBS)) smart membrane separator. A potential below −400mV from the energy harvester applied to the supercapacitor turns the smart membrane separator ‘ON’ and results in a unidirectional ionic current of Li+ ions. As the potential developed by the harvester cycles above ∼50 mV, the membrane separator switches ‘OFF’ and prevents the discharge of the rectified current. This leads to a continuous polarization of ions towards electrical fields relevant for powering electronics. This article is the first description and demonstration of an energy harvesting and storage system that can directly convert the electrical energy from a vibration energy harvester into electrochemical energy without the use of passive circuit components for power rectification.

Full textAbstract:
Structural systems are often composed of multiple components joined together at localized interfaces. Compared to a corresponding monolithic system, these interfaces are designed to leave the load carrying capability of the system unchanged and the resulting effect on the system stiffness is minimal. Hence the mode shapes and frequencies of the dominant structural modes are relatively insensitive to the presence of the interfaces. However, the energy dissipation in such systems is strongly dependent on the joints. The microslip that occurs at each interface couples together the structural modes of the system and introduces nonlinear damping into the system, effectively altering the observed damping of the structural modes. This work develops equations of motion for a jointed structure in terms of the structural modal coordinates and implements a reduced-order description of the microslip that occurs at the interface between components. The interface is incorporated into the modal description of the system through an existing decomposition of a series-series Iwan interface model and a continuum approximation for microslip of a elastic rod. The developed framework is illustrated through a discrete three degree-of-freedom system.

Full textAbstract:
The increasing demand for "exotic" telescope mirrors for space applications has prompted the examination of alternate materials and fabrication approaches. These mirrors must not only have the finely finished, precise, and stable optical surfaces generally characteristic of telescope mirrors, but they must also possess high stiffness and natural frequency and low mass or areal density. A highly efficient substrate structure is, therefore, an implicit requirement. Traditionally, mirrors have been made from glassy materials that are easily figured and polished, are thermally stable, have poor structural properties and are not amenable to fabrication into efficient structural configurations. Clearly, improved material properties and structural configurations could both reduce the mass and improve the structural characteristics of mirror substrates. A unique precision forming process developed by United Technologies Optical Systems can produce precise, complex, thin-section, monolithic formations of silicon carbide (SiC) that combine excellent material properties and highly efficient structural characteristics and offers the potential to achieve the lightweight, high performance telescope mirrors required for space. An example of this technology is shown by the inset photograph.

Interdigitated surface and guided-wave transducers have only recently received attention as possible tools for non-destructive testing. This may be due in part to the increasing attention being paid to piezoelectric polymers as practical transduction materials for structural sensing and actuation. However, much remains to be done to produce a rugged, monolithic device oriented toward these sorts of applications, to characterize and optimize its passive and active response, to develop excitation strategies and signal processing algorithms that in tandem can be employed for arrayed structure monitoring applications. In this paper we confine ourselves to the first two topics and report on the development and proof-of-principle testing of a monolithic interdigitated polyvinyldine fluoride (PVDF) transducer. Specifically, we report on the design and response of an interdigitated transducer with relatively large finger spacings. The finger spacing yield measureable responses in the asymptotically slow single-mode region of Lamb wave dispersion behavior for frequency-thickness products which may be useful for nondestructive testing of many mechanical and civil structural systems.

Full textAbstract:
The positioning accuracy of computer numerical control machines tools and manufacturing systems is affected by structural deformations, especially for large sized systems. Heat induced deformations, long-period deformation of foundations, and the manufacturing process itself, cause time-dependent structural deformations of the machine body, which are difficult to model and predict. In fact, the feasibility of a model-based error prediction is often limited by the complexity of the problem from both the geometrical and the physical point of view. As a consequence, only limited success has been achieved in active error compensation based on the modeling of the relationship between the generalized dynamic loads and the structural deformation field. This paper illustrates a different approach in active error compensation, which exploits a new measurement system, currently in the patenting process, able to measure, in real time, the machine structural displacement field, without any model for the dynamic structural behavior. The first part of the paper illustrates the working principle of the measurement system, which can be described as coupled hardware and software subsystems. The hardware subsystem is basically a triangular mesh of struts, whose nodes are rigidly connected to the underlying structure under measurement. The struts are instrumented with Fibre-optic Bragg Gratings providing their longitudinal strain values. The software part is an algorithm, which evaluates the discrete displacement field by computing the node positions on the basis of the strut longitudinal deformations. The second part of the work focuses on the performance, in terms of accuracy, resolution, and time stability, of a prototype of the above described measurement system. Finally, the third part illustrates two major enhancements on the system design: the design of a monolithic variant of the reticular structure (with higher performances and reduced cost), and a different computation algorithm providing increased accuracy and limited error propagation.
