Abstract
Stress fields of anti-plane finite elastic solids containing hole subjected to the traction or displacement boundaries are studied by using the method of fundamental solutions (MFS) in this paper. The conformal mapping technique is applied to achieve the robustness in computation for the anti-plane elastic problem. The performances of the MFS utilizing the direct MFS method and the MFS based on the conformal mapping technique are studied in solving multi-connected anti-plane elastic problem. Based on the complex analysis, the approximate solution of the complex analytic function is derived for the MFS. To avoid the derivatives on the traction boundaries, a modified boundary condition utilizing the value of the analytic function is given to construct the interpolation equations. Furthermore, the interpolation equations are given in the mapped plane by the conformal mapping technique. The accuracy of the solutions of stress with the MFS is compared between the direct MFS method and the MFS based on the conformal mapping technique in three numerical examples of the traction boundary and the mixed boundary conditions. It is illustrated that stress fields obtained by the MFS based on the conformal mapping technique can achieve good accuracy for the multi-connected anti-plane problems, whereas the direct MFS can not. The proposed method is an expansion of the traditional MFS in solving the elastic problems and can be applied for the heat transfer and the electrostatics problems with the simple concept and the easy numerical implementation.
