摘要
本文是文献[1]的续篇,具体介绍多裂纹弹性柱体扭转问题的边界配置法和其数值计算中所采取的各项措施。在所附的五个算例中有四个是从未解过的。计算结果进一步证明了,本法可以计算任意截面具有任意多条外裂纹受扭轴的抗扭计算惯性矩和各裂纹尖端的应力强度因子。
The work in this paper is the continuation to ref.[1]. The boundary collocation method for solving multi-cracked elastic prismatic shaft torsional problem and the concrete key to the settlement of the numerical calculation and its process are discussed in detail. Out of the five calculating examples raised, four have not been solved before. The calculating results have further proved that this method can be effectively used to calculate the rigidity and stress intensity factor at each crack-tip for any arbitrary cross-section with edge cracks of torsional shaft.
