Dispersion analysis of Lamb waves propagating in anisotropic functionally graded plates with transverse inhomogeneity reveals that the high frequency asymptotes associated with the interfacial Stoneley waves disappear, while in stratified plates the corresponding high frequency asymptotes exist. The analysis utilizes a variant of the Cauchy sextic formalism coupled with the exponential fundamental matrices for constructing explicit dispersion equation.

关于功能梯度板中消失的斯通利波

在具有横向不均匀性的各向异性功能梯度板中传播的兰姆波的色散分析表明，与界面斯通利波相关的高频渐近线消失了，而在分层板中存在相应的高频渐近线。该分析利用了柯西性别形式主义的一种变体，并结合了指数基础矩阵来构造显式色散方程。
