A numerical method for the Cauchy principal value of the singular integral in BEM is developed using the concept of finite part integration under integral variable transformation. It is applied to the numerical integration on isoparametric element successfully, as shown in the examples in this paper.The project supported by National Natural Foundation of China. |
