CONSTRUCTION OF A MODEL OF NONLINEAR DEFORMATION OF SPATIALLY-REINFORCED FIBER MATERIALS WITH DISORDERED FIBERS

A model of nonlinear deformation fibrous materials multidirectional reinforcement with misoriented fibers and a physically matrix is proposed. spatially reinforced material regarded as multicomponent random arrangement fibers. It based on stochastic differential equations the theory elasticity. The solution to problem stress-strain state effective properties composite constructed by method conditional moments L.P. Khoroshun. An algorithm for determining deformative has been developed. taking into account its physical nonlinearity an iterative method. law connection between macrostresses macrostrains in dependence average strains stresses have established. Material curves are plotted various values fiber volumetric content. content studied. influence investigated. established that significant effect materials.
