摘要：
In this paper, we describe a numerical model for the calculation of drawbead restraining force. The model is formulated using an elasto-plastic finite deformation finite element method. Due to bending, unbending and reverse bending deformation during the sheet metal passing through the drawbead, a kinematics hardening constitutive law associated with a description of cyclic property and Bauschinger effect is considered. Comparing with the experiments, we find the results based on kinematics hardening material model are proved to be better than those based on usual isotropic hardening material model.
