THEORY OF PLASTIC STRAINING FOR STRUCTURAL-HETEROGENEOUS COMPOSITE MEDIA

The aim is to construct the effective defining equations within the frames of the flow theory on base of the known component properties for the wide class elastic-plastic component media and also to develop and investigate on their base the concrete models of the plastic composite materials with different microstructure. The systematic analysis of the basic regularities for transfer from local defining equations to the correlations on the microlevel within the frames of the flow theory has been performed. The compound defining equations for two-phase medium as an associated law with piecewise-smooth loading surface have been obtained. Two approaches for constructing the defining equations of the composite multiphase medium have been proposed: method for direct calculation of tensor of effective tangent moduli and multilevel continued model on base of the pairwise-phase combination. The models of the real composite materials with reinforcing inclusions of the different shape have been constructed. The rigid-plastic model of the fibrous composite has been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
