Abstract: A simple mathematical model for calculating drawbead restraining force is derived by the deformation analysis of sheet metal passing through a drawbead. Plane strain assumption is employed. While the anisotropy, strain rate sensitivity and Bauschinger effect are taken into account. The calculated results are compared with experimental ones correspondingly and the validity of this model is verified.

Key words: Anisotropy, Bauschinger effect, Drawbead restraining force, Plane strain, Strain rate sensitivity
