正交各向异性弹性层/压电半空间结构中Love波的传播特性

Propagation Characteristics of Love Waves in Piezoelectric Half-space with Orthotropic Layer

研究了层状半空间介质中Love波的传播特性,其中表面层为正交各向异性纯弹性材料,而半空间为横观各向同性压电材料。推导了显函形式的频散方程,并结合数值算例分析了压电材料的性能和正交各向异性的程度对传播速度的影响。

The propagation of Love wave is investigated in the layered structure consisting of an orthotropic elastic layer and a piezoelectric half-space. The dispersion equation is obtained in explicit form. The numerical examples are provided to show the influences of the orthotropic degree and the properties of piezoelectric materials on the dispersion behaviors of the Love wave.
