In order to achieve reliable but cost - effective crash simulations of stamped parts, sheet - forming process effects were incorporated in simulations using the ideal forming theory mixed with the three - dimensional hybrid membrane and shell method, while the subsequent crash simulations were carried out using a dynamic explicit finite element code. Example solutions performed for forming and crash simulations of I - and S - shaped rails verified that the proposed approach is cost effective without sacrificing accuracy. The method required a significantly small amount of additional computation time, less than 3 % for the specific examples, to incorporate sheet-forming effects into crash simulations. As for the constitutive equation, the combined isotropic - kinematic hardening law and the nonquadratic anisotropic yield stress potential as well as its conjugate strain - rate potential were used to describe the anisotropy of AA6111 - T4 aluminum alloy sheets.
