摘要
多裂纹受扭轴问题,目前能解得结果的还仅限于几种简单形状截面存在某些特珠的规则裂纹的情况。本文提出了一种应力函数的特征展开式,用边界配置法可解决任意形状截面存在任意外多裂纹受扭轴的抗扭刚度和第三型应力强度因子问题。
For multi-cracked torsional shaft, for the time being, only some particular problems with simple-shaped cross-section and regular cracks have been solved. In this paper, a new stress function characteristic expansion equation is presented. Accompanied with the boundary collocation method, the torsional rigidity and K(?) problems of any arbitrary externally multi-cracked cross-section can be solved.
