Purpose - development of mathematical models, techniques and software for the calculation of the stress-strain state of composite rotation shells with defects inter layers of technological and operational origins. Quantitative estimation of the influence of delaminations on strength of responsible shell constructions under the actions of operating loads. Research methods - finite element method, the methods of computational mathematics, modern software development technologies. On the basis of the approximation method of Legendre polynomials with the exact satisfaction of the boundary conditions on the faces the solving equations by for composite shells minimum order are obtained. On the basis of the relations the refined theory of composite thin-walled structural elements developed numerical methods and computer simulation of deformation of layered shells in the operating conditions, taking into account the delaminations at the interfaces.
