| Abstract: | When plastic FEM is used to numerically simulate the process of sheet metal forming, handling of dynamic contact interface conditions between the workpiece and its dies is needed to obtain credible computational results. In this paper, based on comprehensive analysis of the dynamic variation of the contact interface between the workpiece and its dies, material methods to identify and handle the dynamic interface conditions are presented. Through analysis of the specific example, the feasibility of the methods is proved. |
