Abstract
The article discusses a range of issues related to the design of ship structures made of composite materials. To form the surface of such structures, natural stiffness elements are often used, which determine the shape and functionality of the product, and at the same time ensure its strength and rigidity. These include angles, corrugations, curvature and similar elements, which are analyzed in the article by serial calculations using finite element methods and batch analysis of laminates. The factors of reducing the weight of structures due to stiffness elements are highlighted. A review of the normative methods of accounting for these elements in different rules has been carried out and recommendations for their implementation in domestic regulatory documents have been given. The necessity of a fundamentally different approach to the design of structures made of composite materials is emphasized.
