Abstract

The present paper investigates the electromechanical coupling and the propagation of Bleustein–Gulyaev (B-G) wave in a transversely isotropic piezoelectric composed half-space under the effect of initial stress. It also addresses the dispersion relation of the Bleustein-Gulyaev wave. The suitable electrical and mechanical boundary conditions are considered for the electric potential, and electric displacements. The dispersion relation is computed numerically and illustrated graphically for the electric open and short cases for different thicknesses of the layer and wave number under the effect initial stress. The results indicate that the Bleustein-Gulyaev wave and electro-mechanical coupling factor are influenced by initial stress and the physical properties of the material. Numerical outcomes are produced employing LiNbO3 as an example of the materials included for clarification. Bleustein-Gulyaev waves under the initial stress have a good deal of practical importance in different signal transmission, micro-machined gyroscopes, sensors, actuators, signal processing and information storage applications
