Abstract:
OpenSees is an object-oriented open-source finite element software platform suitable for advanced simulation of structural and geotechnical systems. Lacking of powerful pre-processor, the preparing of input scripts for OpenSees is time consuming and error-prone for large and complex models. Patran is an excellent pre-processing commercial package for finite element analysis and offers the powerful Patran Command Language (PCL) for user customization. Taking the advantage of Patran in finite element pre-processing, the finite element modeling is done in Patran and the input script for OpenSees is generated by PCL. It is an alternative approach to efficient pre-processing for OpenSees.

Abstract:
This paper aims to demonstrate the structure analysis of strut-braced wing of a typical manufactured Light-Aircraft by using FEM software (MSC PATRAN/NASTRAN) and determine the safety margin in all of its components, which are useful to determine the structure strength requirements. The geometrical model of the wing was created in CATIA and then exported to PATRAN, which is the modeler to build the finite element model. PATRAN model geometry was modified and prepared to create the mesh. The structural components have various functions and shapes, thus different element mesh was created. After creating the finite element model for all parts, the elements and material properties were assigned and the model was fixed at the spar root edge and strut-braced end, and loaded by distributing the inertia load and aerodynamic load, calculated using (CFD), acting on the rib edge. Then the model was submitted to NASTRAN for linear static analysis. The obtained Stress Results and Safety Margins of each part were calculated and found to be acceptable.

Abstract:
The United States Army contracted Boeing-Sikorsky to develop the RAH-66 Comanche, a new, armed reconnaissance helicopter that features stealth technology designed to improve survivability when operating in hostile environments. Ballistic testing is required on any new technology, including the Comanche, prior to fielding. This thesis uses computer programs called PATRAN and DYTRAN from MSC Software Corporation to build a model and simulate the effects of an explosive round detonating in the Comanche tailcone section. This thesis describes in great detail the process of creating and modifying the model in PATRAN to most accurately depict the Comanche tailcone section, and of creating the input decks for DYTRAN to run the analysis. A test case involving an explosion with a high amount of explosive energy, or specific internal energy (SIE) was simulated. From this test, several results are shown to display the capabilities of DYTRAN. These results, when compared with live fire data, can be used to validate the computer-based simulation in order to reduce the requirements of expensive live fire testing.

A segurança operacional da malha de dutos de transporte de hidrocarbonetos é uma grande preocupação de todas as companhias de petróleo, devido aos imensos danos econômi-cos, sociais e em termos da imagem da companhia que um acidente de grande porte com um duto pode causar. Esta malha deve ser monitorada continuamente e problemas encontrados devem ser avaliados de forma confiável, a fim de analisar o comprometimento da integridade estrutural do duto e permitir que reparos necessários sejam realizados com segurança, antes que estes defeitos causem um acidente. No caso de defeitos causados por corrosão, a análise computacional com o Método dos Elementos Finitos (MEF) tem se mostrado uma das ferra-mentas mais eficientes para a avaliação correta da integridade estrutural de dutos com defei-tos. Estas ferramentas permitem considerar diretamente os fenômenos físicos envolvidos no processo de falha do duto resultando assim em resultados mais precisos que os encontrados por meio de modelos semi-empíricos e bem mais rápidos e econômicos que os obtidos através de experimentos em laboratório. A análise via o MEF, no entanto, requer uma grande especialização e um treinamento específico que não são característicos de todos os engenheiros de tubulações. O processo para a criação de bons modelos computacionais para um defeito, que inclui a modelagem fiel da geometria deste defeito e a geração de uma malha apropriada, demanda uma interação manual constante do engenheiro, é demorado e muito repetitivo, e por estas razões muito propenso a erros. Normalmente, este procedimento é repetido desde o início para cada novo problema analisado, em um patente desperdício de recursos humanos qualificados. A principal proposta deste trabalho foi desenvolver um conjunto de ferramentas com-putacionais que produzem automaticamente modelos de dutos com defeitos, prontos para se-rem analisados em programas comerciais que implementam o MEF, a partir de alguns parâ-metros que localizem e forneçam as dimensões principais do defeito ou de uma série de de-feitos. Estas ferramentas são baseadas no programa comercial de pré e pós-processamento MSC.PATRAN e foram produzidas por meio da linguagem de programação PCL (Patran Command Language). O programa de geração automática de modelos (denominado programa PIPEFLAW) tem interface gráfica simplificada e personalizada, de forma que um engenheiro, com noções básicas de simulação computacional com elementos finitos, possa gerar rapida-mente modelos que resultem em simulações precisas e confiáveis. A realização das análises não-lineares foi feita por meio de um script implementado na linguagem de programação PYTHON a partir do qual toda a análise é gerenciada através da execução automática de tarefas pré-determinadas. Assim, a cada iteração da análise, o sol-ver ANSYS é acionado pelo script e em seguida, os resultados gerados durante aquela iteração são lidos e interpretados pelo script possibilitando que os critérios de convergência e incremento de carga, pré-definidos pelo usuário, sejam aplicados automaticamente, diferen-temente do procedimento usual quando se ativa os critérios de convergência e de incremento de carga determinados pelo solver . Por fim, são apresentados alguns exemplos de modelos de dutos gerados automatica-mente pelo programa PIPEFLAW. Os resultados de análises numéricas, realizadas utilizando as ferramentas desenvolvidas neste trabalho, são comparados com resultados empíricos, nu-méricos e experimentais disponíveis na literatura com o objetivo de validar as ferramentas aqui apresentadas

Os dutos para transporte de petróleo e gás são um dos meios mais seguros e que menos agridem ao meio-ambiente, além de possuírem uma alta eficiência e produtividade. Mesmo tendo uma capacidade excepcional, eles são uma grande fonte de preocupação das companhias petrolíferas e estão sujeitos a diversos tipos de defeitos, dentre os quais o que mais se destaca são os defeitos causados por corrosão. Então, para que uma malha dutoviária opere com segurança, faz se necessário monitorar continuamente ela, para que defeitos encontrados sejam analisados de maneira rápida e confiável, verificando-se assim a integridade estrutural da região afetada. Neste contexto, a análise computacional pelo Método de Elementos Finitos (MEF) tem-se mostrado uma poderosa e eficiente ferramenta na avaliação estrutural de dutos com defeitos causados por corrosão, pois os resultados obtidos pelo método são mais rápidos e econômicos do que os conseguidos pelo método experimental, e bem mais precisos do que os obtidos pelos métodos analíticos. Ampliar com segurança a vida útil dos dutos transformou- se para os engenheiros uma tarefa fundamental e muito importante. Este trabalho teve como proposta, o desenvolvimento de um programa que automatizasse a geração de modelos computacionais identificados de defeitos utilizando malhas estruturadas e não estruturadas (malhas mistas) no mesmo modelo, através da implementação de funções escritas em linguagem de programação PCL (Patran Commando Language) e adicionadas ao programa PIPEFLAW (Cabral, 2007) desenvolvido pelo grupo PADMEC. Também foram construídos modelos computacionais de dutos com defeitos de corrosão com geometria irregular. Para a criação dos modelos foi empregado o programa comercial de pré e pósprocessamento MSC.PATRAN. Depois de concluídos, todos os modelos foram avaliados estruturalmente através da realização de análises não-lineares. Para esta etapa utilizou-se o programa comercial de simulação numérica o solver ANSYS. Por fim, são apresentados alguns exemplos de modelos de dutos gerados automaticamente, que utilizam malha mista, pelo programa PIPEFLAW. Os resultados dessas análises numéricas realizadas são comparados com resultados empíricos, numéricos e experimentais quando disponíveis na literatura. Também são apresentados alguns exemplos de modelos de dutos com defeitos de corrosão com geometria irregular construídos, e os resultados das análises numéricas realizadas nestes modelos para o estudo de suas capacidades estruturais

Full text
Abstract:
The aim of this work is to evaluate the mechanical strength of a co-polymer of 2-hydroxyethylmethacrylate (HEMA) and methylmethacrylate (MMA), so that it can be applied as an interfacial layer between bone cement and steel implants to improve their performance and life. Finite element (FE) analysis techniques are used to assess the behavior of the interface layer under static and dynamic loading conditions. The material property of the co-polymer is a function of its composition and water saturation. The factors affecting the strength of the bone-implant interface are many. Implant interfacial fracture can lead to decreased stability. Fatigue life is a very important process in failure. The results obtained from static and dynamic analyses show that increasing the percentage of HEMA improves the strength of the interface by reducing the stiffness of the implant, absorbing more energy and by reducing the interfacial stress peaks and making the stress distribution more nearly uniform.

Abstract:
La nature et les acteurs d'un site web ont considérablement évolués depuis leur apparition en 1996 : les premiers sites diffusaient de l'information statique et étaient réalisés de manière artisanale par peu d'acteurs, alors que désormais, ils sont devenus un vecteur privilégié d'informations dynamiques, de dialogue entre les utilisateurs et sont réalisés par des équipes projets faisant intervenir de multiples compétences. Cette évolution a conduit les concepteurs à faire face à un ensemble de critères de plus en plus contraignants pour répondre de manière toujours plus rapide à la mise en œuvre de fonctionnalités interactives évoluées, mais les nombreux travaux de l'ingénierie du web, de la réutilisation ou centrés sur les modèles ne répondent pas totalement aux attentes des concepteurs. Ce mémoire propose la méthode WISDOM, dont les objectifs sont de guider le concepteur dans le processus de conception d'un site web, de formaliser et de réutiliser une expérience de conception issue de l'analyse de sites web en production, de caractériser des composants logiciels par des informations fonctionnelles et non fonctionnelles pour aider à les choisir et de proposer une architecture logicielle d'accueil pour faciliter le développement du site lui-même. Implémentée au sein du WISDOM Tool, cette méthode a été utilisée pour concevoir la nouvelle version du site web du LAMIH, mais sa validation et celle de l'outil sont examinés par rapport aux nombreux sites web pour la conception desquels (et à partir desquels) la méthode a été conçue et utilisée.

Abstract:
Paterae cover approximately 2% of the surface of Io, Jupiter’s volcanically active moon. To understand the formation of these volcano-tectonic depressions we created a geologic map of a key region and compared this map with experimental models for Io paterae. Our mapping region is Tupan Patera, a patera that has experienced recent activity and is a detected hot spot. We identified four primary types of geologic materials: plains, patera floors, flows, and diffuse deposits. We constructed an experimental model to test previous suggestions that paterae may form as volatiles in the silicate crust are vaporized by rising magma, creating instability, and subsequent collapse. The apparatus is a scaled model that uses sand (silicate crust analog), ice or snow (volatile analog), a hotplate (magma chamber analog), and a moveable paddle (to simulate extension). Our experimental collapse features exhibit many characteristics of paterae on Io, such as “islands,” terraces, straight margins, and steep scarps. Our model suggests that the role of volatiles in Io’s crust is a significant part of paterae formation.Comparative studies between our map and model show it is possible Tupan is an emerging lava lake or one in a state of quiescence. Our studies have also culminated in the completion of a theoretical cross section for the geologic history of Tupan Patera. This cross section displays a sequence of events including the rise of magma as it preferentially volatilizes sulfurous layers in the crust, subsequent thinning, instability, and collapse, the likelihood of the patera floor sinking as a stoped block, and the more recent flow and diffuse deposits. This study gives some insight to the general formation of paterae on Io.

Abstract:
The method of pipeline inspection data usage for needs of numerical analysis of technical condition of pipeline is considered. A real crude oil pipeline was taken into considerations to make numerical assessment of stress state in case of large deformations which were measured by an intelligent caliper inspection tool. The pipeline was rested on concrete supporting blocks in a boggy terrain. The tool detected very large deformations of the pipe in the areas of these supports which were caused by washouts. Data from the tool were processed into the format readable for MSC/PATRAN-graphical pre-processor of the computational system MSC/NASTRAN based on the Finite Element Method – FEM. Then a mesh of discrete model was generated by means of MSC/PATRAN.

Abstract:
Abstract Based on conical screw matrix transformation, equations of variable pitch conical helix and helicoid are derived. The surface geometry of a trapezoidal threaded variable pitch conical lead screw is generated by a trapezoid with a variable pitch conical screw motion. A computer-aided design code is developed with Patran Plus solid modeling. The result of this work is necessary for the computer-aided machining of trapezoidal threaded variable pitch conical lead screws.

Abstract:
Abstract With the recent advances in the various fields of engineering and the fields of computer hardware and software, a large number of computer programs are being used as design tools in the area of manufacturing. These tools generally deal with parameters and variables specific to one particular area. For instance, a solid mechanic code is equipped with means of specifying forces and displacements and a program designed for magnetics analysis can only have input/output related to magnetics. However, in many realistic systems, a number of these various fields are present and effective design requires coupling of these variables.

Abstract:
Computer models are abstractions of physical reality and are routinely used for solving practical engineering problems. These models are prepared using large complex computer codes that are widely used in the industry. Patran/Thermal is such a finite element computer code that is used for solving complex heat transfer problems in the industry. Finite element models of complex problems involve making assumptions and simplifications that depend upon the complexity of the problem and upon the judgment of the analysts. The assumptions involve mesh size, solution methods, convergence criteria, material properties, boundary conditions, etc. that could vary from analyst to analyst. All of these assumptions are, in fact, candidates for a purposeful and intended effort to systematically vary each in connection with the others to determine there relative importance or expected overall effect on the modeled outcome. These kinds of models derive from the methods of statistical science and are based on the principles of experimental designs. These, as all computer models, must be validated to make sure that the output from such an abstraction represents reality [1,2]. A new nuclear material packaging design, called 9977, which is undergoing a certification design review, is used to assess the capability of the Patran/Thermal computer model to simulate 9977 thermal response. The computer model for the 9977 package is validated by comparing its output with the test data collected from an actual thermal test performed on a full size 9977 package. Inferences are drawn by performing statistical analyses on the residuals (test data – model predictions).

Abstract:
As part of our “What Is Just Tech?” series, we invited several social researchers—scholars, practitioners, artists, and activists—to respond to a simple yet fundamental question: “What is just technology?” This interview was conducted by Just Tech program officer Catalina Vallejo, who spoke with Desmond Upton Patton, Professor of Social Work at Columbia University and Just Tech Advisory Board member. Patton (he/him) studies how gang-involved youth conceptualize threats on social media and the extent to which social media may shape or facilitate youth and gang violence. He is the founding director of SAFElab, which centers young people’s perspectives in computational and social work research on violence, trains future social work scholars, and actively engages in violence prevention and intervention. In their conversation, Vallejo and Patton spoke about social media as an amplifier of violence, the importance of lived experience informing computational research, and misunderstandings about Black grief.
