Mathematical model of destruction kinetics dislocations in cutting plastoelastic workpiece material
The article presents an analysis of rheological kinetics models of materials destruction in the process of cutting, based on the theory of dislocations. The criteria for ductile and brittle fracture mechanism of workpiece material during cutting are established. A system of equations, describing the behavior of termoelastoplastic workpiece in the process of its mechanical processing based on classical thermodynamic analysis, is given.
