Implementing process analysis - Methods for calculating constraints

This article presents elementary methods for approximate resolution of the plasticity equations for metals. They are applied to the analysis of forming processes and mechanical tests. The metal is, in general, a rigid perfectly plastic solid (RPP) and satisfies the von Mises plasticity criterion. Tools are rigid, and metal/tool interfaces are subject to Tresca friction.

It is divided into 2 parts:

• the article on "energy methods" [M 3 007] ;

• this one for "stress calculation methods" [M 3 008] .
