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. Using
the solutions of the problem, the stress intensity factors mode III are determined and their dependence on the sizes of the
areas of cracks filled with injection material, the distance between them and the thickness of the filler are analyzed
