Original Abstract

The work deals with a finding of a suitable technique for the calculation of a Generalized Stress Intensity Factor for the case of the crack terminating at the interface of two different anisotropic materials. For solution, a two-state integral method, especially so-called -integral, is used. An assumption for this analysis is a knowledge of eigenvalues and eigenfunctions of the appropriate singular solution. We use a path independence of the two-state integral and the Finite Element Analysis which provides relatively accurate values on integration paths remote enough from the concentrator. For a solution of the singularity exponent the Implicit method is used. This method is also useful for finding of the auxiliary solution which is required in interactive integrals.
