The investigation of power mode with the upper bound method in the combined radial extrusion processes with flange form by hollow part considered. The compared different kinematics module – the kinematically possible velocity field and the advantage of curved triangular module defined. The resulting general solution can be extended to cases simple radial extrusion process with flange form on external and inner surface of hollow part. Comparison of theoretical and experimental results specially pressure values deformation showed the acceptability of the dependences obtained for technological calculationsReferences
