The domain integral method 问询
在看Contour integral evaluation的帮助文档时，发现里边说到了一个The domain integral method 的方法，但是没具体说怎么操作这种方法，想请问一下大神们，这种方法是怎么回事，怎么操作的。谢谢附上帮助文档原文
The domain integral method of Shih et al. (1986) provides a useful method for numerically evaluating contour integrals for the J-integral, stress intensity factors, and T-stress. This method provides high accuracy with rather coarse models in two dimensions; in three dimensions coarse meshes still give reasonably accurate values. It adds only a small increment to the cost of the stress analysis and can be specified easily. 有没有大神懂呀 可以看看这篇文章：A disk-shaped domain integral method for the computation of stress intensity factors using tetrahedral meshes
