The analytical solution of the ball-stopper forming problem by stamping a cylindrical tubal workpieces in hemispherical dies

Abstract

The analytical solution of the stress-strain condition problem in process of a cylindrical tubal workpiece stamping by hemispherical dies is given. The accuracy of the solution is affirmed by solving in FEM applications and by the experiment. The solution enables to use experimentally defined models of boundary friction and mechanical properties оf the material.
