External load turns the orientations of spontaneous polarization in microscopic domain structures of piezoelectric materials. This domain switching in microscopic structure dominates macroscopic piezoelectric performance. This paper presents a multiscale nonlinear finite element method through a crystallographic homogenization method to analyze ferroelectric hysteresis behaviors caused by domain switching. As a computational example, the electric field-strain relations were discussed for BaTiO_3 single crystal with various initial orientations.
