초록

Finite element method is very effective method to simulate the forming processes with good prediction of the deformation behaviour. In this paper, It was focussed on the drawability factors on the square cup deep drawing by PAM-STAMP with using magnesium alloy to reduce car weight as well as to draw much attention from the viewpoint of environmental preservation high rigidity, In order to predict the effect of drawability factors, the relationships between punch load and punch stroke, the relationships between thickness strain and distance, and are used. According to this study, the results of simulation will give engineers good information to access the drawability of square cup deep drawing at warm temperature.
