| Research Abstract |
Numerical model for mechanics of materials including the multi-scale relationship between microstructure and macroscopic material properties was developed based on multi-phase-field model. Mechanical properties of each phase were taken into account, and the modeling for investigating the effect of complex shape and morphology of microstructure on the macroscopic behavior was constructed. Availability of the developed model was validated by demonstrating simulations on microscopic stress distributions in polycrystalline material and lamellar structures. Molecular dynamics model was also developed to focus on the physical situation at the two-phase interface, and the influence of the properties of each phase on the macroscopic properties was investigated.
