| 摘 要： | 本文导出了任意厚度的三层固体复合媒质中Lamb波特征方程式,给出了相邻固体层之间重要的两种界面条件(刚性联接和滑移联接)时Lamb波色散曲线。我们也计算了不同界面状况时Lamb波两个最低阶模式(对称模式s0和反对称模式a0)所产生的质点位移沿厚度方向的分布。

| Abstract: | The characteristic equation for Lamb waves in three-layered solid composites with arbitrary thickness of each layer are derived in this paper.Two important boundary conditions,i.e.rigid and slip boundary conditions,between neighbored layers are considered and the dispersion curves with different boundaries are demonstrated.Numerical computations of the particle displacement distributions along the thickness direction are made for the lowest normal modes s0 and a0 |
