摘要：

This paper proposes a model which predicts the feasibility of deep drawing operations of thin plates for various directions of solicitation. The first part consists of a theoretical presentation and a comparison of experimental results. The influence of anisotropic parameters and their implications for the surface stress criteria are then analysed. It is possible to predict the optimal direction of solicitation (in direct or broken path) to increase the strains during deep drawing operations by using this approach. Finally, we propose a modification of the model to improve understanding of the influence of rate strain on forming limit stress and strain diagrams. (C) 1998 Elsevier Science S.A.
