ABSTRACT
This work presents the analysis of stresses required for a frictionless equal-channel angular pressing (ECAP) of perfectly plastic or strain-hardening materials using finite-element method and upper-bound type analysis. Upper-bound type and FEM analysis were analytical approximations and numerical methods respectively. The two methods used and presented agree well for different ECAP die angles and materials.
