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