Abstract
A new KAVF(kinematically-admissible velocity field) is proposed to determine the forming load, the average extruded length and the flow pattern is the extrusion/forging process of polygonal headed bars. Experiments are carried out with lead billets at room temperature using regular polygonal shaped punches. The theoretical predictions of the forming load and the average extruded length are in good agreement with the experimental results.
