| Outline of Final Research Achievements |
A new hot-working multiscale model, which can simulate the microstructure evolutions and the macroscopic mechanical behaviors simultaneously, has been developed. This model is called the multi-phase-field and finite element dynamic recrystallization (MPFFE-DRX) model, where the microstructure evolutions are simulated by the multi-phase-field method and the macroscopic mechanical behaviors are computed by the conventional finite element method for the elastic-plastic large deformation problem. By performing the nonuniform compression simulations of a cylinder, an availability and validity of the developed MPFFE-DRX model have been investigated. In addition, we started the study to develop more accurate dynamic recrystallization model by coupling the crystal plasticity finite element method and multi-phase-field model.
