MATHEMATICAL MODELLING OF THE PROCESS OF PLASTIC DEFORMATION OF MATERIALS

The article describes the urgent issue of the application of mathematical modeling methods for the study of the process of plastic deformation of materials. The research suggests to use efficiency factor of energy dissipation as the optimality criterion of thermomechanical parameters of hot materials working. Techniques of computational mathematics were used for the experimental verification. The analysis of constructed mathematical model revealed certain regularities in the dependence of the efficiency of energy dissipation on the temperature and strain rate of the processed material.
