摘要
采用格林函数方法研究界面圆孔对SH 波散射的远场解答.在构造格林函数并求解界面圆孔对SH波散射及其近场解答的基础上,继续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,分析了不同材料组合而成的界面圆孔对SH
The far field solution of SH wave scattered by bimaterial structure possessing interface circular hole by the use of Green’s function method is investigated. When a special Green’s function has been constructed and close field solution has been illustrated, the far field of scattered wave is studied. 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.
