Analysis of the strength of an infinite matrix with a single-periodic array of healed cracks under torsion load

A boundary-integral approach for the study of the stress-strain state of an infinite body-matrix with single-periodic array of cracks healed by a ductile material and under static torsion loaded is proposed. The ptoblem is reduced to solving a system of 2-d boundary integral equation with respect to an unnown jump functions of shear displacements of defect surfaces.
