Abstract

The magneto-thermo-mechanical behavior of metals in inductive heating devices is investigated by means of numerical calculations. The goal of this paper is to attract attention to necessity of mechanical problems solution for inductive heating technology and to develop three-dimensional and two-dimensional (axisymmetrical) mathematical models, coupling algorithm and software for such computations. The paper presents a finite element formulation, based on an indirect coupling model of electromagnetic, thermal and static elastic-plastic mechanical processes in treated workpieces in inductive heating devices. The effect of electromagnetic, thermal and mechanical material properties depending on temperature is taken into account. The presented numerical technique is applied for technological problems of practical interest.
