Abstract

Wrinkling of workpiece is one of the major problems occurring at application of impulse drawing of thin sheet metal. The loss of shell stability appears in the areas with compressive stresses and is basis of buckling phenomenon. The nonlinear explicit finite element code LS-DYNA was used for prediction wrinkling. Pulse pressure and strain hardening of a material were given from experiment. The modeling of shell such as Belytschko-Wong has given the good consent of results of finite element simulation of sheet metal forming process with experimental data at electrohydraulic thin brass drawing.
