This article considers a method of modeling combined extrusion process based on the hypothesis of force and kinematic similarity of deformation parameters. It also shows the expediency calculation of plasticity resource in the combined extrusion through failure criterion that takes into account the influence of the third invariant of the stress tensor on the plasticity of blanks deformed under three dimensional stress state.
