Simulation of Multi-pass ECAP by 3D finite element method

摘要：

Multi-pass ECAP process of pure Al for square samples (Φ=90°, ?=37°, pressing speed of lmm/s), was simulated by using 3D finite element method (FEM).The distribution of equivalent strain for two and four passes was compared. The results showed that route A leads to non-uniform distribution of equivalent strain during multi-pass ECAP. The distribution of equivalent strain is uniform in Be route, but the value of equivalent strain is larger in C route. The simulation results were compared with the experimental ones with previous work in the literature. The simulation also shows that equivalent strain and load increase with pass increasing.
