Forced Electromechanical Vibrations of a Sodium-Chloride Plate.
Abstract
A recent extension of the classical theory of elastic dielectrics, to include an interaction between strain and polarization gradient, admits the possibility of excitation of electromechanical vibrations in crystals with a center of material symmetry; i.e., those in which there can be no classical piezoelectric effect. The new equations are applied to a case of forced thickness vibrations of a plate of sodium chloride crystal and the fundamental frequency, mode shape and electromechanical coupling coefficient are calculated--all subject to an assumption, regarding boundary conditions, which can be tested experimentally.
