摘要
采用Ｇｒｅｅｎ 函数方法研究界面固定圆形刚柱对ＳＨ 波散射的远场解答．首先给出含有半圆形刚柱的弹性半空间的水平表面上任意一点，承受时间谐和的出平面线源荷载作用时的位移函数．其次，取该位移函数作为Ｇｒｅｅｎ 函数，推导出定解积分方程．最后研究该问题的散射远场，给出了散射波远场位移模式和散射截面的解答．通过具体算例。
The far field solution of SH-wave scattered by bimaterial structure possessing interface cylindrical rigid inclusion by use of Green's function method is investigated.Constructing a special Green's function firstly,the integral equation is set up.The displacement mode of scattered wave at far field and scattering cross-section are given.Numerical results are illustrated and the influence of different combinations of bimaterial structure on scattered wave at far field is discussed.
