Modeling Electrostrictive and Ferroelectroelastic Materials

Electrostriction Coupling

Electrostriction is an interaction between the mechanical and electric physics, where an electric field applied on electrostrictive material generates the deformation of the material (direct effect), and a stress applied on it changes the material polarization (inverse effect). In contrast to linear piezoelectricity, the electrostrictive strain induced in the polarized material is proportional to the square of the polarization. Thus, the strain will remain the same if the direction of the applied electric field is changed to the opposite.
