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 analyzing 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 factors using the results of a numerical solution to 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.
