Abstract

The electro-mechanical behavior of ferroelectric materials is studied by a joint experimental and numerical investigation. The experiments were performed on lead zirconate titanate PIC151 (PI Ceramics) samples, and the numerical simulations were done by a 2D Finite Element implementation of a continuum phase field model. To limit computational costs, the material is idealized as a single crystal. The phase field parameters for the material are determined through experimental parameter identification. Numerical results are presented to show the domain structure evolution within the crystal. In comparison to experimental results, calculations are carried out to disclose mesoscopic properties of the material under various poling scenarios, the dependence of the coercive field on the electric loading frequency, and the improvement of the material properties by stress-assisted poling procedures.
