Induction heating is more efficient for plate bending because of its easy operation and control of working parameters compared with heating by a torch. In this study, a more efficient method was proposed for the prediction of plate bending. The conventional analysis method using the axis symmetric coil model could not handle the varying temperature during the heating and forming process for curved plates with a convex, a concave, or a twisted curvature. The proposed method using some discrete divisions and steps in this study could overcome these difficulties and show more accurate, reasonable results of temperatures and deflections in flat or curved plates. This method is composed of multidisciplinary analyses such as an electro-magnetic analysis, a heat transfer analysis, and a deformation analysis based on inherent strain method and elastic deformation analysis.
