摘要
本文通过区域的连续映射推导了一种映射半解析边界元法,将其应用于界面裂纹问题的动力分析,可大大减小计算工作量。典型算例的结果表明,本文方法是非常有效的,并可推广应用于三维复杂形状裂纹的计算问题。
Based on continuous domain mapping,this paper develops a mapping semi-analytical boundary element method. Applying it to dynamic analysis of 3D interfacial cradk computational work will be greatly reduced. Typical examples demonstrate the efficiency of the method and its application to 3D arbitrary shaped crack analysis.
