Solution of the problems of antiplane deformation for bodies with thin ribbonlike inclusions by the methods of integral equations. II. Analysis of the stress concentration and stress intensity

On the basis of pure physical reasoning, we deduce the relationship between the stresses acting at the tip of a defect and the coefficients of root singularity of the stress field, i.e., the generalized stress intensity factors. We propose approximate relations for the evaluation of the generalized stress intensity factors. The efficiency of the proposed approach is demonstrated by comparing the results of numerical analyses of specific problems performed by using the proposed and direct approaches.
