Abstract: The coupled electromagnetic, thermal and mechanical simulation is described for new technological processes of induction heating of large steel disks. Non-uniform temperature distribution of induction heated disks may cause plastic deformations and buckling. The goal of this investigation is to determine the mechanical behaviour of induction heated disks by means of coupled finite element computation in different formulations. The paper contains the detailed description of an applied numerical technique and of obtained results including elastic-plastic stress distribution, plastically deformed state and the most likely modes of the disk buckling.
