在这项工作中，建立了双边界元方法，以有效地模拟动态裂纹问题。采用静态基本解，利用对偶互易技术将惯性项的域积分转化为边界积分。根据裂纹张开位移计算动应力强度因子。利用子区域技术，与准各向同性和各向异性结果进行了比较。通过实例验证了该方法的准确性和有效性。版权所有©2004 John Wiley & Sons， Ltd
In this work, the dual boundary element method formulation is developed for effective modelling of dynamic crack problems. The static fundamental solutions are used and the domain integral, which comes from the inertial term, is transformed into boundary integrals using the dual reciprocity technique. Dynamic stress intensity factors are computed from crack opening displacements. Comparisons are made with quasi‐isotropic as well as anisotropic results, using the sub‐region technique. Several examples are presented to assess the accuracy and efficiency of the proposed method. Copyright © 2004 John Wiley & Sons, Ltd.
