In this paper, we analyze SH waves propagating in the layered structure consisting of a functionally graded piezoelectric (PE) layer and a piezomagnetic (PM) half-space, where the surface of the PE layer is electrically and magnetically open. The solution of the coupled fields and the dispersion relation are derived. The numerical results are given to show the effect of the gradient coefficient and...
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...
This paper investigates the thickness-twist waves propagating in an infinite piezoelectric-piezomagnetic bi-material plate. The upper and lower surfaces of the plate are assumed to be mechanically free, electrically open and magnetically closed. The exact solutions of the thickness-twist waves are derived. As an example, for the propagation of the thickness-twist waves in the bi-material plate consisting...
Elastic wave propagation along the axis of a piezomagnetic cylinder imperfectly bonded by a piezoelectric layer is studied. The characteristic of the imperfect interface is expressed by the radial and the axial stiffness coefficients. The influences of the electro-magnetic boundary conditions, interface imperfection and geometry of the cylinder on the dispersion relations of elastic wave are discussed...
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...
