This paper derives an explicit dispersion equation of SH waves propagating along the interface between a piezoelectric (PE) and a piezomagnetic (PM) half-space. It is assumed that the interface has a magneto-electro-elastic imperfect bonding. A general linear spring model, considering the spring constants of mechanical, electric and magnetic fields, simultaneously considering the coupled spring constants...
This paper investigates Love waves propagating in the layered plate structure consisting of a piezomagnetic layer and an orthotropic piezoelectric half space. The Love waves can propagate in the resulting structure and the dispersion relations of the Love waves are obtained. In the case of a Terfenol-D layer over a KNbO3 substrate, the wave exists at any rotated cut. The results showed that the phase...
We analyze the propagation of gap waves between two half-spaces of functionally graded piezoelectric materials (FGPM). The material properties of the half-spaces vary in the direction perpendicular to their surfaces. It is found that there exist waves that can propagate in the gap and near the surfaces of the half-spaces. The speed of these waves is sensitive to the thickness of the gap and the material...
This paper, investigates the dispersion characteristics of shear horizontal (SH) surface waves propagating in a piezoelectric (PE) layer imperfectly bonded on a piezomagnetic (PM) half-space. Both the layer and half-space possess the hexagonal symmetry. The so-called shear-lag model is used to describe the interfacial property. The surface of the PE layer is traction-free, electrically closed and...
