ABSTRACT

A numerical framework for the simulation of sheet steel stamping forming is presented. The main problems, the equations of motion, the constitutive relation, the initial conditions, boundary conditions and contact conditions, are presented in detail. Based on this, the finite element model is established and solved for exploring the changes in laws of stress, strain and so on. The information on stress, strain and load displacement is obtained at different deformation stages. The numerical results show that the finite element algorithm can effectively simulate the deformation process of sheet steel which helps to explain that the numerical framework is feasible for sheet steel stamping forming problems.
