Numerical method for determining a stress intensity factor in the case of solids of homogeneous and heterogeneous materials with a crack

Algorithms for determining the stress intensity factor are developed on the basis of the results of the analysis of asymptotic solutions to the problems of deformation of a homogeneous solid with a cut and a plate with a crack located at an interface between two media,. The proposed algorithms are used to calculate stress intensity coefficients using the results of a numerical solution of the problems of loading various flat and spatial homogeneous cracked solids, as well as a plate with a crack located at the interface between two elastic media. It is shown that the calculation results are in good agreement with the data obtained by other methods.
