Abstract

In the present study, 2D plain strain finite element simulation was conducted to analyze the rotary-equal channel angular pressing (R-ECAP) process. Two different routes were considered during simulations: one with applying unidirectional die rotation and another with alternative reversion of the direction of rotation (RR-ECAP). Plastic strain distribution, flow net, pressing force and damage development during these two R-ECAP routes were analyzed. Results showed that the pressing force increased with deformation passes and reached a steady state value. Also plastic strain distribution in the sample was more uniform in case of RR-ECAP process.
