Metal Flow Prediction in Forging and Extrusion Using Ubet

  • Chapter
Proceedings of the Twentieth International Machine Tool Design and Research Conference

Abstract

A generalised technique for the prediction of load and metal flow in forging and extrusion type operation is presented. The method is based on the upper bound elemental technique and simulates the process in an incremental manner. Details of results obtained for closed die forging, extrusion and simultaneous compound extrusion are given.
