摘要
本文使用边界积分方程方法（ＢＥＭ）与迭代优化技术，建立了一种以静态边界位移测量为补充信息的裂纹识别方法，迭代中正问题的求解，采用了作者提出的高精度边界积分方程算法，结果表明在测量点充分、选位合理的前提下，该方法具有收敛快。
In this paper, by applying of the boundary integral equation method and iterative optimization technique, a crack identification method based on the static displacement measurement is given, where the normal problem is solved by author′s high precision boundary integral equation method. The results show that the method proposed is of faster convergence and higher identification precision if the measuring points are enough and properly selected.
