RHEOLOGICAL BEHAVIOR AND STRENGTH OF COMPOSITE SYSTEMS OF THE TYPE "ALUMINUM OR ITS ALLOY (POLYMER)- OXIDE CERAMICS-CHROMIUM CARBIDE"M. V. Kireitsev UDC 621.763:539.4 Rheological methods are proposed and on their basis methods for calculating strength and load characteristics of composite systems of the type "aluminum or its alloy (polymer)- oxide ceramics-chromium carbide" have been developed. The rheological behavior of systems under their local loading has been considered. The results of the comparison between the calculated and experimental results have confirmed the adequacy of the developed models and methods. Allowable specific contact pressures of composite systems have been established.
