Напружено-деформований стан композиційних матеріалів

Abstract

High productive rock cutting tools is made of structural materials, which the inherent hardness and much much plasticity. These properties have a two-phase composite materials, which are obtained by using circulating molds. In a stream of molten metal that poured into the back mold, poured carbide granules. Due to centrifugal forces, they move into the molten metal matrix to the outer surface of the working parts. When it is cooled from the crystallization temperature of the metal to the room in the volume of the resulting product having the stress strain state due to the difference of thermal linear expansion coefficients of materials of a viscous matrix and granules armitora with considerable firmness. In this paper we study the features of stress strain state of composite materials and developed a method for calculating the mechanical stresses of the system "metalosvyazka - spherical granules armitora.
