Developed method of boundary integral equations in case of determination of stress concentration in anisotropic plates around the openings, elastic and rigid inclusions and cracks considering contact of the coast. Developed numerical algorithms of finding the voltages were adapted to the proposed methods of calculation for strength of composite structural elements. The developed technique allows to evaluate the stress-deformation state of anisotropic plates with curvilinear cracks, including branched. Known method of calculation of durability of isotropic plates based on the study of the kinetics of growth of fatigue cracks (including with account of contact of their banks) in case of composite plates was generalized.
