摘要

研究了平面弹性波在各向异性层中的衍射问题。衍射问题被简化为层的边值问题。采用网格法求解得到的边值问题。考虑了平面纵波经该层的衍射。本文对纵波能量流法向分量的增益频率和增益角特性进行了数值研究。

On Peculiarities of Propagation of a Plane Elastic Wave through a Gradient Anisotropic Layer

The problem of diffraction of a plane elastic wave by an anisotropic layer is studied. The diffraction problem is reduced to a boundary value problem for the layer. The grid method is used for solving the resulting boundary value problem. The diffraction of a plane longitudinal wave by the layer is considered. Some peculiarities of the gain-frequency and the gain-angle characteristics of a normal component of an energy flow of a passed longitudinal wave are numerically studied.
