Structure-energy model of the wear resistance of metallic materials in heterogeneous continua
This paper describes the elastic state of heterogenous materials within the framework of the mechanics of heterogenous continua. Failure condition of a two-phase material is formulated and the dependencies of hydroabrasive and cavitational wear of steel on the spacing of the inclusions of martensite in steels with ferritic-cementitic and austenitic structures are established. The dependence of the wear resistance criterion on the stress, distribution density and austenitic grain diameter is also presented. The results made it possible to develop an effective structure-energy model to describe wear processes of materials and coatings.
