Abstract  An isotropic medium containing a system of foreign transverse rectilinear inclusions is considered. Such a medium can be interpreted as an infinite plate, reinforced with a regular system of stringers, whose cross sections are very narrow rectangles. Medium is weakened by a periodic system of rectilinear cracks emanating from the contours of the holes. The action of the stringers is replaced by unknown concentrated forces at the points of their connection with the medium. The boundaryvalue problem on the equilibrium of the periodic system of cracks is reduced to a singular integral equation, from the solution of which the stress intensity factors are found. The condition of limiting equilibrium of cracks is formulated based on the criterion of brittle fracture.
