The purpose of the work is to develop methods for designing fibrous composites with given ratios of effective elastic moduli and damping parameters in different directions. The technical task involves the creation of new methods of designing composite materials with the necessary parameters of anisotropy of physical properties based on the complex use of numerical methods of stress state analysis of structural elements and numerical methods of homogenization of composites. Research methods – theoretical methods of homogenization of nonlinear mechanical properties of composite materials, computer methods of calculating the parameters of composite materials. Methods of theoretical determination of effective elastic properties of fibrous composite materials have been developed. Micromechanical analysis is performed on a periodically repeated representative volume based on the finite element method. Product Description popup.authors Vodka Oleksii О.
