Eigenvibrations of a piezoelectric plate of thickness-shear vibrations with an arbitrary convex surface

Abstract

The paper addresses an analysis of the thickness-shear vibrations of a piezoelectric resonator affected by a convex anisotropic boundary surface. We show that anisotropy of the boundary surface strongly influences the eigenvibrations. Generic relations are given to calculate the frequency spectrum and distributions of the vibrations amplitudes with normal drive levels.
