Abstract: A kinematically admissible velocity field which is different from Avitzur's has been proposed for axial symmetrical rod drawing and extrusion.An upper-bound analytical solution in cylindrical coordinates has been obtained without any mathematical simplification in this paper.

Key words: drawing, extrusion, velocity field, upper-bound power
