Description

The report on the NTP consists of one volume: 60 p., 26 fig., 2 tables, 8 literary sources. SOFTWARE, VERIFICATION, INTERLAYER DAMAGES, FINITE ELEMENT METHOD, LAYERED COMPOSITE SHELLS Research object – the bearing capacity and residual strength of structures from layered composites in the presence or occurrence of damage to the surfaces of the section. Purpose of the work – development of software that implements a mathematical model of deformation of layered composite shells with structural defects. Research methods – finite element method, the methods of computational mathematics, modern software development technologies. On the basis of the developed mathematical model of deformation of the method of winding of layered composite shells of rotation for discrete consideration of structure by thickness, the software for solving the problems of determination of three-dimensional ability and residual durability in the presence or occurrence of damages on the surface of sections in typical shells was created. The research results are published in the papers [2 – 8].
