A method for calculating stresses in the structure of a pressure cylinder made by winding a composite fibrous material has been developed. A special feature of the proposed method is that the problem is solved within the framework of the 3D formulation of the problem of the theory of elasticity, considering the curvilinear anisotropy of the structure, which changes from point to point. This technique allows one to consider the detailed microstructure of a composite material wound with overlapping tapes. To solve the problem, the 3D finite element method is used, as well as a special algorithm for constructing an additional mesh of elements, which makes it possible to relate the curvilinear anisotropy with the geometry of the thin-walled shell under study.
