This paper describes deformation analysis of a piezoelectric plate considering ferroelectric properties. Analytical model is a thin disc. Electric displacement in the thickness direction and normal strain in the radial direction of the disc subjected to harmonic external electric field in the thickness direction are analyzed on the basis of the electromechanical constitutive relations and the rate law considering domain switching. The graphical representations of the strain and the electric displacement with the electric field form butterfly loop and hysteresis loop, respectively. Numerical examples are presented to examine how the loops are effected from the amplitude and the frequency of the external electric field.
