PROGRAM IMPLEMENTATION OF THE ALGORITHM FOR THE DETERMINATION OF EFFECTIVE DEFORMATIVE PROPERTIES OF PHYSICALLY NON-LINEAR LAYERED-FIBROUS MATERIALS OF A OBLIQUE-ANGLED WINDING

Abstract

A model of nonlinear deformation of layered-fibrous composite materials of oblique-angled winding under physically nonlinear deformation of components is formulated. Algorithms of determination of their effective deformative properties and stress-strain state is constructed. The nonlinear deformation of layered-fibrous composites is investigated. Deformation curves for different types of simple loading are constructed. Influence of a nonlinearity of the deformation of components and value of winding angle on the effective deformative properties of composite materials is studied. It is established that the nonlinearity of the components and value of winding angle significantly effect on the effective deformative properties and stress-strain state of layered-fibrous composites.
