Abstract

Computer simulation of new methods for material processing is a multidisciplinary analysis and requires the development of special software with appropriate mathematical models and algorithms. In this paper, a program for finite element modeling of phenomena associated with the release of Joule heat in inhomogeneous systems is created. Using the developed program, a model system simulating a polydisperse powder material was investigated. In the model, an electric current flows through the powder material. The model material has a matrix structure with round-section particles. The parametric model is characterized by different conductivity, concentration, and mutual arrangement of particles. The possibility of obtaining an anisotropic structure as a result of thermal action on the powder material during the flow of electric current was shown. A list of control parameters of the technological process for obtaining anisotropic powder material was established. A method for system analysis of computer simulation results using diagrams similar to phase diagrams of multicomponent compounds was proposed.
