On the generalized expression of the configuration force acting on the interfaces and domain boundaries in ferroelectric polycrystals

Abstract

The expression of the force acting on the interfaces and domain boundaries in ferroelectrics is obtained, the difference in their electrophysical properties being allowed. It is shown that the additional contribution to the configuration force due to the difference between the piezoelectric constants of the domains results in the bending vibrations of the boundaries excited parametrically by a variable external field.
