| 摘 要： | 本文基于Betti互等定理,给出一组薄板弯曲问题的基本解;它们都是薄板基本方程的奇异解。将它们应用于薄板弯曲断裂分析时,提供了一个求应力强度因子的新途径。本文引用了Hadamard积分主值概念。最后举了一个算例。

| Abstract: | Based on Betti's reciprocal theorem, a set of fundamental solutions to bending problems have been given. They are singular solutions to fundamental equations of thin plates. By these fundamental solutions, a new way for computing the bending stress intensity factor is proposed. In this paper Hadamard's principal value of the singular integral is used and an example is given. |
