证明了当边界条件满足一定的条件时,裂纹问题解的梯度在表面断裂裂纹的每一个尖端都发生爆破。在此基础上,我们提出了一种算法,用于检测的位置,方向和强度的尖端的表面断裂裂纹。
We prove that the gradient of the solution to the crack problem blows up at every tip of surface breaking cracks if the boundary data satisfy a practical condition. On the basis of this result, we propose an algorithm for detecting the location, the orientation, and the intensity of the tip of a surface breaking crack.
