We investigate the dispersive behavior of shear horizontal (SH) surface waves propagating in a layered structure consisting of a piezoelectric layer and an elastic half-space, in which the top and bottom of the layer are electrically shorted. The interface between the layer and the half-space is assumed to be imperfect bonding. The degree of imperfection of the interface is described by the so-called shear-lag model. The dispersion equations are expressed in an explicit closed form. The phase velocities are calculated to show the influences of the interfacial imperfection and the material properties of piezoelectric layers on the dispersive characteristics.
我们研究了在由压电层和弹性半空间组成的层状结构中传播的水平剪切（SH）表面波的频散行为，其中层的顶部和底部被电短路。假设层与半空间之间的界面为不完美结合。界面的不完美程度由所谓的剪力滞后模型来描述。将色散方程表示为显式封闭形式。计算了相速度以显示界面不完美和压电层的材料性质对频散特性的影响。
