The purpose of this study is to reveal nonlinear behaviors caused by domain switching and structural phase transition. The homogenization theory was employed for scale-bridging between macrostructure and microstructure. Crystal morphologies, which were characterized as an inhomogeneous structure composed of many grains and domains with individual orientations, were modeled at a microscopic scale. Then nonlinear response of the macrostructure was evaluated through monitoring microstructural crystal morphology change. The proposed simulation was applied to a polycrystalline PZT (lead zirconate titanate) at MPB.
