1. Estudo da análise de fadiga pelo MEF considerando os efeitos da estampagem / Study of fatigue analysis by FEM considering the metal stamping effects
As simulações dentro do ambiente de projeto devem prever a utilização de novas variáveis, especialmente de processos, de forma a aumentar a proximidade entre os modelos virtual e real e, com isso, aumentar a precisão das simulações. O objetivo deste trabalho foi o de estudar um modelo pelo Método dos Elementos Finitos que incluísse os efeitos da va

2. Eletroerosão por fio em metal duro para ferramentas de estampagem de lâminas de motores elétricos
The process of wire electrical discharge machining is currently used in manufacturing most hard metal (tungsten carbide) dies and punches, used in steel stamping tools for electric motors. The home appliance, industrial electric motor, transformer and hermetic compressor industries, use progressive stamping tools, justifying a better understanding of the man

3. Estudo analítico-numérico de freios de estampagem em chapas metálicas / A hybrid approach for estimating the drawbead restraining force in sheet metal forming
In order to get a better part quality in sheet metal forming, the rate of the material flow into the die cavity must be efficiently controlled. This control is made by a restraining force supplied either by the blankholder, the drawbeads or both. When the restraining force required is too high, the use of drawbeads is necessary, although excessive deformatio

5. Study on formability in hydroforming steel sheets tailored welded blanks / Estudo da conformabilidade na hidroconformação de recortes de chapas de aço soldados a laser
The increasing number of vehic1es and a more rigorous environmental legislation, are forcing automobile industries and research centers to develop new materials and manufacturing processes to the production of parts with higher mechanical properties, better formability and sheet thickness reduction, without comprirnising the rigidity and structural stability

6. Study about the drawability, in the solid state, of the thixocast A5052 aluminium alloy and the viability of its thixodrawing / Estudo sobre a estampabilidade, no estado solido, da liga de aluminio A5052 tixofundida, e viabilidade da sua tixoestampagem
This work presents an analysis of the viability of drawing A5052 sheets in the semisolid state. Initially, to produce thixocast sheets, rolled commercial sheets were submitted to partial melting by different temperatures and holding times, to analyse the sheets draw ability in the solid state. The parameters utilised were: 627°C for 5 and 10 minutes, and 63

9. Simulação do processo de estampagem profunda de corpos cilindricos atraves do metodo dos elementos finitos
Deep drawing process change the geometry of a metal sheets to complex shapes. The complexity of the geometry and many variables involved make the tool design very difficult. The recent necessity of quicker developments in the manufacturing methods make necessary to review this tool design and to simulation methods have become very important. It was used the
