Abstract

A method of metal flow, load and strain prediction in forming operations is presented. Based on the upper-bound elemental technique, it is applied to hot forging operations where a constant flow stress can be assumed and also to cold working of aluminium and steel where the effects of strain hardening are taken into account. The predictions were found to be in reasonable agreement with experimental results.
