Abstract

An elastic-plastic finite element formulation is presented for three dimensional deformation analysis of sheet metal forming operations. The updated Lagrangian type formulation is based on membrane theory to analyze the large strain-large displacements. The sheet is considered isotropic that obeys Mises flow theory. The deformation is rate-insensitive and work-hardening property of the material is incorporated. Coulomb friction is applied between the sheet and punch and sheet and die interfaces. Triangular flat elements are employed in the finite element discreatization. Comparison of the finite element results with the experimental data is also given.
