Abstract

Analytical methods for determining the elasticity constants of unidirectional composite materials, such as the rule of a mixture, model of coaxial cylinders, model Kilchinsky and model Vanin are considered. The main assumptions made in the calculations are reduced to the fact that the fibers and the matrix are isotropic elastic materials, which, when loaded, are deformed together, which is ensured by the presence of a rigid connection between them. The calculations of elastic characteristics are presented and a comparative analysis of the chosen approaches is performed on the example of layered composite materials. Recommendations concerning the expediency of using the considered methods are made.
