Simulation Results

Finite element analysis was used to simulate the evolution of damage in a Mg–3Al–1Zn alloy processed by equal channel angular pressing (ECAP). Oyane criterion for damage was selected to evaluate the fracture characteristics. Finite element modeling was used with experimental data obtained from tension and compression testing. The results show that initial crack may form in severe flow localization (i.e. in the inner corner) and these cracks may propagate, leading to billet segmentation. The flow grid in the simulation results is similar to that in the previous experimental results.
