A new kinematically-admissible velocity field is proposed to determine the final-stage extrusion load and the average extruded height in the backward extrusion of internally non-axisymmetric tubes from round billets. The proposed velocity field is applied to the backward extrusion of internally troc

In this paper a new upper-bound approach is used to analyze the tube extrusion process. A kinematically admissible velocity field is developed to evaluate the internal power and the power dissipated on frictional and velocity discontinuity surfaces. The total power is optimized with respect to the
