摘要
借助于边界积分方程方法提出了一个适用于界面裂纹问题的无单元法.通过对不同情况界面共线裂纹问题的数值模拟,分析了界面裂纹之间的影响,算例证明该方法有效,且精度较高.
In virtue of the advantage of boundary integral equation, a boundary mesh-free method is developed to study the interaction between the collinear interfacial cracks. The cases of two and three collinear cracks are numerically simulated and computed, and the interaction between them is analyzed. This method has been proved accurately and effectively by the present example.
