Propagation Behaviors of SH Waves in Piezoelectric Layer/Elastic Cylinder with an Imperfect Interface

Abstract:

The dispersion behaviors of SH waves are investigated propagating in a layered structure consisting of a piezoelectric layer and an elastic cylinder. The interface between the piezoelectric layer and the elastic cylinder is assumed to be imperfect bonding. The surface of the piezoelectric layer is assumed to be mechanically free and electrically shorted. The dispersion equation is derived by the basic equations, the boundary and the interface conditions. The numerical examples are provided to show the influences of the imperfect interface, the thickness ratios and the material properties of the piezoelectric on the dispersive characteristics.
