    An effective method for analyzing interaction behaviors of multiple through-cracks subjected to complex loading

    • 摘要: 对任意二维型裂纹群,受复合载荷作用时的相互干涉效应,本文提出了改进型体积力法。改进之一是采用以每个裂纹中心为基点的相对坐标变换法;其二是采用间接法有效地处理了积分奇异性。计算结果同文献数据相比较,表明了本法更为高效和精确。

       

      Abstract: The improved body force method is proposed for analyzing interaction behaviors of arbitrary multiple through-cracks under complex loading. Two improvements are made: One is the adoption of relative coordinate transformation against each crack centre and the other is the treatment of integral singurality by Proposed indirect method.In comparison with available data published, the results obtained show that the proposed method is an effective one for analyzing interaction behaviors of muitiple through-cracks subjected to complex loading.
