Abstract

Various industrial applications require fully coupled electromagnetic-thermal-structural (ETS) solution. However, the fully coupled ETS technique has rarely been reported. This is mainly due to the difficulty of transferring the displacement from a structural analysis to an electromagnetic analysis in many commercial FEM codes. In this paper, a fully coupled ETS model was constructed with a morphing technique to consider this transfer. This model and a conventional segregated model were then applied to simulate induction heating process of plate bending. It is found that the results with the fully coupled model significantly differed from those with the segregated one. The difference can be attributed to the fact that the former model has changed the air gap between the inductor and the plate in the electromagnetic analysis. Furthermore, the proposed model was modified to compare with the segregated model that has been validated by highly precise experiment. The comparison shows the good agreement.
