摘要
研究了功能梯度材料层状结构中Love波的传播特性 .对覆盖层中的剪切弹性模量沿厚度方向为指数函数和幂函数变化的两种函数形式 ,利用WKB方法分别求得了波传播问题的近似解析解 ,通过计算分析 ,得到了Love波在功能梯度材料层中传播的一些规律 .
The propagation behavior of Love waves in layered structures with functionally graded materials is discussed. Two kinds of functions are assumed for the shear modulus along the thickness in the overlying layer. Based on the two hypothesis and the WKB method, the analytic solution of wave propagation problem are obtained. Some results of propagation of Love waves in functionally graded materials layer are obtained and discussed.
