摘要
采用边界单元法求解弹性波对孔口的散射问题。给出了弹性波散射问题的边界积分方程，针对数值计算中出现的奇异积分，提出了一种改进的把动力基本解分解为正则部分和奇异部分分别计算的方法。最后讨论了Ｐ波和ＳＶ波对圆孔和椭圆孔的散射而引起的动应力集中。
The diffraction of elastic wave is studied by using Boundary Element Method, and the formulation about elastic wave diffraction is given. For caculating singular integral, a improved numerical method which divides dynamic fundamental solution into singular part and regular part is proposed. Finally examples of P wave and SV wave scatter against circular hole and ellipse hole are discussed.
