摘要：

A semi-implicit integration scheme was used to implement the Yoshida-Uemori two-surface model into the finite element method. Hill's quadratic yield function was employed to account for the orthotropic behaviour of the metal sheet. The model was used to predict the cyclic simple shear response of DP-600. In order to evaluate the capability of the model for sheet metal forming, the model was used to simulate both the forming stage of a channel draw process in the presence of drawbeads and the subsequent springback stage. The results show that the model predicts the springback profile very well, especially at deeper drawbead penetrations. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.
