摘　　要：将基本解法首次用于模拟正交各向异性弹性力学问题,讨论了虚假边界的选取对计算结果的影响。数值算例结果与精确解的对比表明,该算法精度高,收敛速度快,较少的节点便能达到较高的计算精度。The method of fundamental solutions was first applied to simulate the orthotropic elastic problems,and the influence of the selection of the false boundary on the numerical results was discussed.In Numerical examples,the algorithm was of high accuracy,fast convergence,and a few nodes can achieve high accuracy by comparing calculated result with exact solution.
