NONLINEAR DEFORMATION OF FIBROUS MATERIALS

Abstract

The nonlinear deformation of fibrous composites is studied in the article. A model of nonlinear de formation of fibrous composite materials under physically nonlinear deformation of components is formulated. Algorithms of determination of effective deformative properties and stress-strain state of fibrous composite materials as well as the deformation curves for different types of simple loading are constructed. Influence of a nonlinearity of the deformation of components on the effective deformative properties of fibrous composite materials is investigated. It is established that the nonlinearity of the components significantly affects on the effective deformative properties and stress-strain state of fibrous composites.
