Paper Abstract

Composites consisting of piezoelectric and piezomagnetic materials have found increasingly applications in acoustic wave devices as well as smart materials and structures. Because of the coupling effects between the electric, magnetic and elastic fields, the mechanics and physics of piezoelectric/piezomagnetic composites are of intensive research interest in recent years. In this paper, the propagation of shear horizontal (SH) waves in a coupled plate consisting of a piezoelectric layer and a piezomagnetic layer is studied. Both layers possess transversely isotropic property and are perfectly bonded along the interface. The surfaces of piezoelectric and piezomagnetic layers are assumed to be mechanically free, electrically open and magnetically closed. Based on the quasi-static electromagnetic approximation, the general solutions of the problem under consideration are firstly derived. The exact dispersion relation is obtained by applying the boundary and interfacial conditions to the obtained general solutions. The numerical results are provided to show the influences of piezoelectric material properties and the ratios of the thickness of the piezoelectric layer to the piezomagnetic layer on the propagation behaviors. The results of this paper can offer some fundamental theory to the application of piezoelectric/piezomagnetic composites or structures.
