摘　　要：本文首先给出了作者推导的两边简支无限长薄板弯曲问题和平面应力问题的基本解，然后运用域外奇点法及给出的基本解分析了一对边简支矩形薄板的弯曲和平面应力问题．计算结果表明，这种方法具有计算量少、精度高等优点。Basic solutions for infinite plate with two sides simply supported subjected to bending as well as to plane stress are first presented. Then the basic solutions and the method of singular points exterior to domain are applied for analysis of rectangular plates with two sides simply supported subjected to transverse as well as to in-plane loadings. Numerical examples are given. It is shown that the proposed method can generate solutions with high accuracy at little computing cost.
