摘要：
Plane stress numerical simulations of elastic-plastic deformations are commonly based on in-plane projected equations. It is shown that in case of the isotropic Von Mises material model the numerical procedure can be simplified and faster when the full 3D yield criterion is used. Plane stress is preserved by plane stress trial stresses in the return mapping procedure.
