Abstract：

The influence of hardening index n values on the deep drawing performance of cylinder for different friction coefficients was investigated by the finite element analysis using PAM-STAMP 2G software. The results show that the limit drawing ratio of the steel sheet is decreased with the increasing of the friction coefficient. There is little influence of hardening index n value on the deep drawing performance at smaller friction coefficient. The influence of hardening index n value on the deep drawing performance grows with the increasing of the friction coefficient. The limit drawing ratio could be increased by the increase of hardening index n value when the friction coefficient is larger.
