将具有守恒性的互积分应用于界面裂纹问题。无限大介质中问题的应力强度因子K_1、K_2、K_3和T-应力很容易通过互积分得到，而不需要求解边值问题。在这样做时，需要辅助解，并且它们取自已知的渐近解。如果考虑有限介质中的界面裂纹，该方法适用于应力强度因子和T应力的数值计算。
A mutual integral, which has the conservation property is applied to the problem of an interfacial crack. The stress intensity factorsK1,K2,K3andT-stress for the problem in an infinite medium are easily obtained by using the mutual integral without solving the boundary value problem. In doing so the auxiliary solutions are required and they are taken from the known asymptotic solutions. This method is amenable to numerical evaluation of the stress intensity factors andT-stress if the interfacial crack in a finite medium is considered.
