Finite Element Analysis Of A Cup Deep Drawing Process [estudo Do Processo De Embutimento Profundo De Copo Pelo Metodo Dos Elementos Finitos]

Deep drawing processes have an important role in manufacturing, mainly in the automotive industry. The increasing competition requires that design and manufacture of dies be fast and without errors. New forms to develop the dies have been used. The finite element method has helped engineers to reduce errors during die development. In this paper an elasto-plastic element was used to simulate the cylindrical deep drawing of an ABNT 1006 steel cup. The simulation made possible the determination of the forces, thickness and circumferential strains occurring during the deep drawing process, which were compared to experimental results.212355363(1993) ANSYS User's Manuals, 1. , (Procedures), 2 (Commands), 3 (Elements) and 4 (Theory), Swanson Analysis Systems IncBathe, K.J., (1982) Finite Elements Procedure in Engineering Analysis, , Prentice-Hall, Englewood CliffsBorst, R., Feenstra, P.M., Studies in anisotropic plasticity with reference to the hill criterion (1990) International Journal of Numerical Methods in Engineering, 29, pp. 315-336Bortolussi, R., (1996) Simulação do Processo de Estampagem Profunda de Corpos Cilíndricos Através do Método dos Elementos Finitos, pp. 81-88. , Dissertação de Mestrado, UNICAMP, cap. 5Bresciani, Fo., Button, S.T., Gomes, E., Nery, F.A.C., Zavaglia, C.A.C., (1996) Conformação Plástica dos Metais, p. 127. , E., Ed.
