Poling of Ferroelectric Ceramics

E. Bassiouny

Abstract:
In this study, we use the model Basic Equations to deduce a one-dimensional model for the description of the poling of ferroelectrics ceramics. This is built within the scheme of the thermo dynamical theory of internal variables. The model produces both plastic and electric hysteresis effects in the form of "plasticity", i.e., rate-independent evolution equations for the plastic strain and the residual electric polarization and both mechanical and electric hardenings. The influence of stresses on ferroelectrics hysteresis loops through piezoelectricity and electrostriction is a natural outcome of this model. Some simple experimental methods for the determination of the material coefficients of the considered ceramics are suggested.
