Abstract：

Based on a virtual power principle,a finite element model for multi\|point forming is given,in which material,geometry and discontinuous boundary condition have been considered. The method dealing discontinuous dynamic contact boundary condition and coulomb friction boundary conditions is introduced. According to classical J 2 flow theory, a multi\|point forming process of square cup is simulated.
