摘要： 本文是文[1]的续篇.对于平行分布的圆盘状裂纹群,文[1]将问题归结为求解一线性代数方程组.对于文[1]中的这一基本线性代数方程组,本文采用摄动法进行求解,导出了以级数形式表示的应力强度因子计算公式.作为示例,本文对大小相等的一对圆盘状平行裂纹的单向拉伸问题进行了计算.数值结果表明,作者对于圆盘状平行裂纹群提出的计算方法是行之有效的.

Abstract: This is Sec. Ⅱ of the paper "Theory and Computations for 3-Dimensional Problems of Multi-Cracks",[1]. With the method and formulations given in[1], here we give numerical results for examples of two parallel oraoks with the same radius but in different planes. Detailed results are ghiven for various oases which indicate the interaction between cracks. It is shown that the method proposed here is quite workable, and the results obtained enlarge the contents of "Handbook of Stress Intensity Factors"[2, 3].
