Abstract: According to the method presented by Li Dong sheng etc.[1],we make use of power model of strengthening to develop the relation between stress and strain.The Bauschinger effect and the normal anisotropy and strain rate sensitivity to establish the model for solving the drawbead restrain forces.The results computed by this model are compared with those obtained by experiment.

Key words: drawbead restrain force, normal anisotropy, strain hardening
