| 抄録: | Evolution of plastic contour of a steel sheet was predicted using various crystal plasticity models, including a phenomenological and dislocation-based hardening model. The evolution of plastic contour was different depending on the model, but none of the models used could predict differential work-hardening behavior observed in experiments. The simulation results showed that the {110} and {112} slip activities were significantly different depending on the stress ratio, suggesting that the differences in the strengths between the {110} and {112} slip systems would play an important role in the evolution of the contour. |
