Abstract

In this paper stress state was determined for tubular billets, using differential equations for equilibrium of volume element and conditions of plastic flow within the restrictions of ratio between normal and tangential stresses on outer and inner surface. Experimental investigations of forming tubular billets are entirely in conformance with FEM numerical simulation which was done using CAMPform 2D software.
