The optimal systems of location of the reinforced ele ments with respect to the cracks and holes at different loading modes have been build, using the above methods. An approach to solution of a complete singular equation with the generelized Cauchy kernel and varying coefficients has been proposed. Calculational models of deformation and fracture of composite materials, taking into consideration the microheterogeneity of structure, stochastic distribution of mechanical properties and physical nonlinearity of materials have benn created. Experimental investigations of polymer glass-plastics and fibre composites, of KDA type, allowed to solve the problem of regulation of strength and relaxion properties of composite in the whole, and the effect of temperature and humidity on material ageing Product Description popup.authors popup.nrat_date 2020-04-03 Close
