文摘
- •
A numerical approach coupling crystal plasticity and cohesive zone method is developed.
- •
Parameters are identified using a homogenization scheme accounting for interfaces.
- •
Simulation results are consistent with experimental curves and observations.
- •
Stress assisted diffusion process should be incorporated in the approach.
