| Abstract: | The analysis of anisotropic thin-body problem with boundary element method involve to singluar and nearly singular integrals which is hard and time-consuming to estimate. In this pa- per, the virtual boundary element method（VBEM） for solving anisotropic thin-body problem in 2D potential theory is presented. It provides a new approach to dealing with such problems. Meanwhile, it extends the application field of VBEM. The numerical results obtained by proposed method prove that the VBEM is not only an efficient tool for solving 2D anisotropic thin-body problems in potential, but also a simple and easily programmed method. |
