The piezoelectric and piezomagnetic effect on the surface wave velocity of magneto-electro-elastic solids

The direction dependence of surface wave speed and the influence of electrically and magnetically short/open circuit conditions are investigated in this paper. First, the elastic, piezoelectric and piezomagnetic coefficients in the considered ordinate system are obtained by Bond transformation from that in the crystal axis ordinate system. Then, the secular equation which surface wave speed satisfies is derived from the free traction condition on the surface of half-space with consideration of electrically and magnetically short/open circuit conditions. Some numerical examples are given. The direction dependence of surface wave speed and the influence of short and open circuit conditions are shown graphically.
