Abstract

Abstract: Strain hardening of pure copper and friction between the sample and die channels is considered for finite element modelling. To validate the FEM results, the FEM calculated effective strain variations were compared with the hardness measurements. Simulated load–stroke curve and peak load calculations were also compared with the experimentally recorded load–stroke curve and peak load. Different stages of the load–stroke curve of the ECAP process was explained in detail. In over all, good conformity is observed between the FEM calculations and experimental results.
