Abstract:

AbstractThe objective of the paper was to determine the level of circumferential stress in a wall of an open milk tank and to assess the tank wall degree of utilization according to the FKM Guideline calculation algorithm − Analytical Strength Assessment of Components, Made of Steel Cast Iron and Aluminium Materials in Mechanical Engineering. (German: FKM – Forschungskuratorium für Maschinenbau). The stress level in the tank wall was determined based on analytical calculations and numerical method using the FEA – Finite Elements Analysis. Numerical calculations were made in FEMAP with NX NASTRAN Solver (NASTRAN – NASA Structure Analysis). Similar stress values were found using two independent calculation methods. The difference between obtained stress values does not exceed 2%. Based on the FKM algorithm, the safety factor jges = 1.4 and static capacity of the tank wall ask = 19.7% were calculated.

Abstract:

Stabilisers are components of the axle suspension system of cars trucks, trains and other moving road vehicles that connect the movement of the two sides of the suspension (right and left) to keep the vehicle levelled. Stabilizers experience bending and torsion at operation. In particular, their arms experience bending while the main body mainly torsional loading. In both cases, the highly stressed area is the surface, where the maximum tensile and shear stresses are acting. High strength steels and special treatments, thermal and/or mechanical, are used for the stabilisers’ manufacturing. The present study deals with necessary input data for fatigue life assessments based on the FKM guideline [1]. In addition, fatigue tests are conducted to calculate the stress-life curves of two different manufacturing processes.

Abstract:

Shrinkage porosities and non-metallic inclusions are common manufacturing process based defects that are present within cast materials. Conventional fatigue design recommendations, such as the FKM guideline (“Forschungskuratorium Maschinenbau”), therefore propose general safety factors for the fatigue assessment of cast structures. In fact, these factors mostly lead to oversized components and do not facilitate a lightweight design process. In this work, the effect of shrinkage porosities on the fatigue strength of defect-afflicted large-scale specimens manufactured from the cast steel G21Mn5 is studied by means of a notch stress intensity factor-based (NSIF-based) generalized Kitagawa diagram. Additionally, the mean stress sensitivity of the material is taken into account and establishes a load stress ratio enhanced diagram. Thereby, the fatigue assessment approach is performed by utilizing the defects sizes taken either from the fracture surface of the tested specimens or from non-destructive X-ray investigations. Additionally, a numerical algorithm invoking cellular automata, which enables the generation of artificial defects, is presented. Conclusively, a comparison to the results of the experimental investigations reveals a sound agreement to the generated spatial pore geometries. To sum up, the generalized Kitagawa diagram, as well as a concept utilizing artificially generated defects, is capable of assessing the local fatigue limit of cast steel G21Mn5 components and features the mapping of imperfection grades to their corresponding fatigue strength limit.

Abstract:

Standard foliar fungicide applications in wheat are usually made between flag leaf emergence (Feekes [FK] 8) and heading (FK10.5) to minimize damage to the flag leaf. However, over the last few years, new fungicide programs such as applications prior to FK8 and split half-rate applications have been implemented, although there are few data pertaining to the efficacy of these programs. Eight experiments were conducted in Illinois, Indiana, Ohio, and Wisconsin from 2010 to 2012 to compare new programs to standard FK8 and FK10 programs in terms of disease control and yield response. The programs evaluated consisted of single full-rate applications of 19% tebuconazole + 19% prothioconazole (Prosaro) or 23.6% pyraclostrobin (Headline) at FK5 (pseudostem strongly erected), FK8, or FK10, or split half rates at FK5 and 8 (FK5+8), plus an untreated check (CK). Leaf blotch (LB) severity and yield data were collected and random effects meta-analytical models fitted to estimate the overall log odds ratio of disease reaching the flag leaf ([Formula: see text]) and mean yield increase ([Formula: see text]) for each fungicide program relative to CK. For all programs, [Formula: see text] was significantly different from zero (P < 0.05). Based on estimated odds ratios (OR = exp[[Formula: see text]]), the two FK8 programs reduced the risk of LB reaching the flag leaf by 55 and 75%, compared with 62 and 69% and 67 and 70% for the two FK10 and FK5+8 programs, respectively, and only 32 and 37% for the two FK5 programs. [Formula: see text] was significantly different from zero (P ≤ 0.003) for all FK8, FK10, and FK5+8 programs, with values of 233 and 245, 175 and 220, and 175 and 187 kg ha−1 for the FK10, FK5+8, and FK8 programs, respectively. Differences in mean yield response between Headline and Prosaro were not statistically significant (P > 0.05). The probability of profitability was estimated for each program for a range of grain prices and fungicide application costs. All FK8, FK10, and FK5+8 programs had more than an 80% chance of resulting in a positive yield response, compared with 63 and 67% for the two FK5 programs. The chance of obtaining a yield increase of 200 kg ha−1, required to offset an application cost of $36 ha−1 at a grain price of $0.18 kg−1, ranged from 44 to 60% for FK8, FK10 and FK5+8 programs compared with 22 and 25% for the two FK5 programs. These findings could be used to help inform fungicide application decisions for LB diseases in soft red winter wheat.

Abstract:

◦ The strength verification according to FKM with FEM results is time-consuming and requires a separate tool, e.g. KISSsoft. ◦ The strength verification was so far only carried out at individual points of the model. The selection of verification points is usually based on the equivalent stresses. The following influences can not or not sufficiently be considered. ▪ Locally different limit value of strain or plastic notch factor ▪ The location of the most critical combination of stress amplitude and mean stress ▪ The local stress gradient ◦ femMeshFKM was developed from ZF for railway applications (IX), where FEM calculations are performed with Permas. Postprocessing was done in Hyperworks. ◦ For ZF Test Systems, femMeshFKM has been extended to use Creo Simulate data. The postprocessing can be done also in Simulate.

Abstract:

Der mit flüssigem Natrium gefüllte Druckbehälter eines Präzessionsexperimentes unterliegt im Betrieb einer Vielzahl an Belastungen. Neben den aus der Rotation und Präzession resultierenden Fliehkräften und dem gyroskopischen Moment müssen ebenfalls die fertigungsbedingten Unwuchten sowie die Fluid-Struktur-Interaktion berücksichtigt werden. Darüber hinaus stellen die bei der Erwärmung bzw. Abkühlung auftretenden thermischen Spannungen eine wesentliche Beanspruchung dar. Es wird ein Algorithmus vorgestellt, der es ermöglicht, alle diese transienten und winkelabhängigen Lasten bei minimalem Rechenaufwand in den Berechnungsprozess einzubeziehen und die für den statischen und zyklischen Festigkeitsnachweis nach FKM-Richtlinie maßgeblichen Beanspruchungen zu identifizieren. Dies ermöglicht die vollflächige Berechnung des Auslastungsgrades in ANSYS Workbench.

Abstract:

Grande parte dos componentes mecânicos e estruturas são solicitados por carregamentos que variam com o tempo e frequentemente falham por fadiga. Neste sentido, é indubitável que o modo de falha por fadiga seja considerado no projeto mecânico de componentes, equipamentos e estruturas sujeitas a carregamentos cíclicos. Os livros de projetos de máquinas ainda são os mais utilizados na indústria como referência teórica e prática ao dimensionamento contra a fadiga de produtos. Entretanto, muitos deles ainda não incluem as últimas descobertas e metodologias mais modernas para o cálculo de durabilidade de estruturas. Adicionalmente, de uma maneira geral, grande parte dos livros especializados em fadiga também não trazem informações detalhadas sobre a previsão de vida em fadiga sob a ótica do projeto mecânico, como a análise utilizando critérios de Fadiga Multiaxial e a análise de fadiga baseada em Elementos Finitos (FE-Based Fatigue Analysis). Baseado neste cenário, este trabalho tem o objetivo de propor um procedimento para avaliar a vida em fadiga de componentes e estruturas reunindo os métodos mais recentes utilizados nesta área. Dentre os vários assuntos incluídos no procedimento proposto, destacam-se: as importantes contribuições propostas pelo Conselho Alemão de Pesquisa em Engenharia (FKM-Guideline); a utilização de Análise por Elementos Finitos (FEA) na previsão de vida em fadiga; o cálculo do fator de tensão média utilizando pseudo tensões provenientes de FEA; a contabilização do efeito de entalhe em componentes com geometria complexa utilizando o Método do Gradiente de Tensão Relativo em conjunto com FEA, que pode ser aplicado tanto em carregamento uniaxial quanto em carregamento multiaxial; a contabilização do dano por fadiga em carregamento multiaxial de amplitude variável; a densidade da malha de elementos finitos adequada para utilizar em fadiga computacional; e a aplicação da teoria e dos critérios de Fadiga Multiaxial, principalmente em FE-Based Fatigue Analyses, cuja utilização é imprescindível em estruturas sujeitas a tensões cíclicas em mais de uma direção (x,y,z).
Most of mechanical components and structures are subjected to time varying loading and therefore often present fatigue failure. Therefore, it is essential to consider the fatigue failure mode in the project of components, machines and structures under cyclic loading. Design of Machine Elements books are still the most used in industry as theoretical and practical reference for designing products against fatigue. However, many of them still do not include the latest findings and methodologies used in fatigue life assessment of structures. Additionally, overall, most of the specialized fatigue books also do not include detailed information about fatigue life assessment in a mechanical project view, as the fatigue analysis using Multiaxial Fatigue criteria and the fatigue life prediction using the Finite Element Method (FE-Based Fatigue Analysis). Based on this fact, this thesis proposes a procedure for predicting component and structures fatigue life, gathering together the most recent methods used in the fatigue area. Among the several subjects included in this procedure, we can highlight: the important contributions of the German Engineering Research Council (FKM-Guideline); the use of Finite Element Analysis (FEA) in the fatigue life assessment; the calculation of the mean stress factor using the pseudo stresses from FEA; the computation of the notch eect in geometrically complex components using the Relative Stress Gradient Method in conjunction with FEA, method which can be applied both in uniaxial loading and multiaxial loading; the estimation of the fatigue damage in structures under variable amplitude multiaxial fatigue loading; the selection of an adequate Finite Element mesh density to use in computational fatigue; and the aplication of the Multiaxial Fatigue theory and criteria, specially in FE-Based Fatigue Analyses, of which use is essential in structures under ciclic stresses in 2 or 3 directions (x,y,z).

Abstract:

Utilizing Building Information Modeling (BIM) for Facility Management (FM) can reduce interoperability costs during the Operations and Maintenance (OandM) phase by improving data management. However, there are technological, process related, and organizational barriers to successful implementation of BIM integrated FM (BIM-FM), and process related barriers might be solved by the use of BIM integrated FM (BIM-FM) guidelines. However, the guidelines need to be updated with lessons learned from actual practices in order to maintain their validity. In order to diagnose current practices and identify key differences between prescriptive representations and actual practices, this exploratory research compares BIM component data requirements between guidelines and actual practices at public higher education institutions in Virginia. The gap in BIM component data requirements between the guidelines and the actual practices may prevent successful implementation of BIM-FM. This research is composed of three parts: a synthesis of prescriptive representations, determination of actual data requirements in practice, and comparison of differences between guidelines and practices. Document analysis and case study via document analysis and in-person interviews were conducted to collect data. Then, direct comparison was conducted to test the research question. Though the researcher disapproved the established hypothesis of 'There would be some differences in BIM component data requirements between prescriptive representations and actual practices' due to the difference in level of information and details between prescriptive representations and actual practices, this exploratory research provides useful information.

Abstract:

Fibromyalgia (FM) is a chronic pain syndrome that is associated with a high level of disability and medical costs. FM is commonly comorbid with migraine and tension-type headache, and is also associated with sleep disturbances, anxiety, and pericranial muscle tenderness Fibromyalgia may be caused by central sensitization, which is also believed to be an important mechanism in the development of chronic headache. Fibromyalgia remains underdiagnosed in the paediatric population, while the early recognition of this syndrome would improve the efficacy of therapy. There are presently no evidence-based guidelines for the pharmacological and non-pharmacological treatment of headache patients with comorbid FM. Amitriptyline has been reported to be efficacious in in migraine, tension-type headache, and fibromyalgia independently, but evidence regarding comorbid headache and fibromyalgia is lacking. Non-pharmacological approaches that have shown promise in patients with chronic migraine and fibromyalgia include transcranial electric and mechanical stimulation.

In this paper the authors selected five kinds of codes, standards and guidelines and compared their fatigue crack growth curves for choice of the suitable curves. The feature of each curve was summarized quantitatively evaluated. JSME maintenance rule and ASME code provide the fatigue crack growth formulae for both ferritic and austenitic steels and consider the environmental effects in some cases. The FITNET curves are categorized in many kinds of metal whereas the FKM guideline and WES procedure provide the common properties applicable to steels generally.

Abstract:

A comparison of currently available codes for assessment of fatigue crack growth, including ASME (America Society of Mechanical Engineers) SEC. XI, FKM (Forchungskuratorium Maschinenbau) guideline, WES (Japan Welding Engineering Society) 2805, BS7910 and JSME (The Japan Society of Mechanical Engineers), was carried out by paying attention to the suitability of application and the easiness to obtain the parameters, based on fatigue crack growth data of Cr-Ni-Mo-V steel welded joints. Results showed that fatigue crack growth curves provided by the FKM or WES were good choice when few inputs were at hand while the curves in the BS7910, JSME and ASME were recommended for precise estimation. It was indicated that the assessment of welded joints solely by fatigue crack growth behavior at base metal part and the assessment of fatigue crack growth for the aged condition by as-received one both resulted in non-conservativeness, albeit dependent on the range of stress ratios, R. A new bilinear form of fatigue crack growth model independent of R was developed based on transition point occurred in the near-threshold regime. This constituted the bilinear approach to fatigue assessment, and thus contributed to the optimization of fatigue assessment in the near-threshold regime.

Conventional flaw assessment procedures are not explicitly developed for situations with large cyclic plastic strains, e.g. for pipelines installed by the Reeling method, and if used indiscriminately may give un-reliable results. In order to resolve this dilemma DNV, TWI and Sintef conducted a Joint Industry Project (Fracture Control for Installation Methods Introducing Cyclic Plastic Strain – Development of Guidelines for Reeling of Pipelines) to provide guidelines on testing and assessment procedures that can be employed by the industry. The project included Materials Testing, FEM Analyses and Validation Testing of Pipe Segments as well as Full Scale Pipes. This paper summarizes the Guideline document that was developed in the project.

Abstract:

To ensure the long-term safe operation of newly constructed Tainter gates, methods of analysis and design criteria are needed in the design stage to assure the dynamic stability of any new Tainter gate. For this purpose, the present study provides a detailed procedure for the dynamic design of Tainter gates that can be applied to preliminary designs by gate engineers to assure the dynamic stability of their gate designs. The dynamic stability of the gate can be determined using the natural vibration characteristics ascertained by finite element method (FEM) analysis, reasonable values of actual structure damping actually measured by the field vibration tests, and theoretical analysis of the coupled-mode self-excited vibration that has been previously established by authors. The procedure and the important points of each step are detailed in an example determination of the dynamic stability of a practical Tainter gate.

Abstract:

This Paper describes the testing of Segment Specimens and Full Scale Pipes carried out at DNV within the Joint Industry Project “Fracture Control for Installation Methods Introducing Cyclic Plastic Strain – Development of Guidelines for Reeling of Pipelines”. The JIP was a cooperation between DNV, TWI and Sintef. A total of 24 full thickness Segment Specimens, with cracks/notches introduced in the Base Metal, Fusion Line Root and Fusion Line Cap, were tested. The specimens were loaded both monotonically and cyclically, simulating reeling installation. Two Full Scale Pipes were subjected to a bending loading program simulating a reeling installation. Each pipe contained three test welds and cracks/notches were introduced both at the 6 o’clock and the 12 o’clock positions, i.e. six cracks/notches in each pipe. In one pipe the cracks/notches were introduced in the Weld Metal and in the other in the Fusion Line from the Cap side. After the loading program all the cracks/notches were broken open and the stable crack growth were measured and compared to predictions based on fracture mechanics principals (essentially following BS 7910-1999). A method for adjusting the analysis procedure, in order to obtain good agreement between the predictions and the experimental observations, is suggested. The JIP also included Materials Testing and FEM Analyses. A Guideline Document was developed which is currently being used by the project participants and it is the intention to issue a DNV Recommended Practice in support of the DNV Offshore Standard OS-F101 “Submarine Pipeline Systems – 2000” based on the experience gained and feed back received from the participants.

Abstract:

Contexto: A falta de rigor na pesquisa em Educação em Engenharia de Software que envolvem participantes humanos já foi examinada em pesquisas anteriores da literatura e pode resultar em evidências questionáveis. Objetivo: Melhorar as condições de planejamento das pesquisas em educação em Engenharia de Software com participantes humanos por meio de um Guideline. Metodologia: Para atingir esse objetivo será realizada uma Revisão Sistemática da Literatura para encontrar lacunas nos aspectos teóricos e metodológicos das pesquisas e Entrevistas com pesquisadores em educação em Engenharia de Software para o relatar os problemas encontrados nas pesquisas. Após, isso um Guideline será proposto através do método Grounded Theory e validado através de Grupos Focais e um Survey. E, por fim um Estudo de Caso será aplicado com pesquisadores em Educação em Engenharia de Software para apresentar as contribuições práticas do Guideline proposto.Link para o vídeo da apresentação: https://youtu.be/0F7jp42nE3I

Abstract:

This paper presents work to create a preliminary set of design guidelines for use in Fused Deposition Modeling (FDM). The experimentation uses build protocol for a Dimension SST Fused Deposition Modeler. Using simulation software known as Catalyst, build time and material volume characteristics of many components of varying size and complexity were calculated. A series of potential guidelines were independently applied to this same set of components. By comparing the new simulated data with the baseline, statistically significant improvements in these two metrics denoted those guidelines which passed a quantitative feasibility test. The results show that six design rules show universal advantage, with two more needing further examination. Future work will lie in examining the feasibility of implementing the changes proposed by the guidelines with respect to desired product functionality. Additionally, correlations related to the application of several guidelines simultaneously need to be determined.

Abstract:

Automotive electronics design and manufacture present unique challenges for product reliability. Recent trends toward mounting electronic systems directly onto engines introduce a new level of severity in terms of thermal and vibration environments. Automotive microelectronic packages experience thermal stresses that can possibly cause components and electrical interconnection damage. The loss of electrical interconnection due to coarse Aluminium wires in electronic modules is one of the most critical reliability problems in automotive electronics packaging. The paper intends to help understand and investigate the reliability of Aluminium wire bonds that make the electrical connection between integrated chips and the leads inside a typical leaded electronic package like TO247. Finite element modeling (FEM) is used to simulate the stresses the package goes through during reliability tests. Results are compared to empirical testing. The FE model consists of the entire TO247 package including the leadframe, overmold, chip, substrate, Al wire loops and corresponding bond pads. Results from simulations provide information to map out high stress locations on the heels of the wirebonds due to package warp. In addition, the results also provide manufacturing engineers the insight to develop general bonding guidelines for Aluminium wires. As a result of this exercise, the development team is able to counter the issue and provide a design guideline to design the leadframe, place components away from high stress locations and pursue a more symmetrical layout to reduce the effect of thermal stresses.

Abstract:

The application of natural and nature‑based features (NNBF) has grown steadily over the past 20 years, supported by calls for innovation in flood risk management (FRM) and nature‑based solutions from many different perspectives and organizations. Technical advancements in support of NNBF are increasingly the subject of peer‑reviewed and other technical literature. A variety of guidance has been published by numerous organizations to inform program‑level action and technical practice for specific types of nature‑based solutions. This effort to develop international guidelines on the use of NNBF was motivated by the need for a comprehensive guide that draws directly on the growing body of knowledge and experience from around the world to inform the process of conceptualizing, planning, designing, engineering, constructing, and operating NNBF.
