摘要：

Computer numerical simulation of non-steady thin-walled half-spherical shell deep drawing is presented. Initial elastic stage of clamped thin workpiece bending followed by the elastic-plastic and rigid-plastic Mises membrane stages with work hardening and wall thickness variation are considered. Tresca yield criterion is used in the region of material biaxial tension. Plastic unload effect induced by non-homogeneous work hardening along the shell generator is included in simulation procedure with the result of good correlation of predicted and experimental drawing force versus punch displacement relation for commercial stainless sheet steel.
