Eddy Current Analysis of Thin Plate with a Conductive Juncture by Line Integral Equations

摘要

In recent years, induction-heating cooker has been disseminated rapidly and it is wished to get flexible and disposable food containers that are available for the cooker. So as to develop a good quality food container that is heated moderately and safely, it is necessary to analyze accurately eddy currents induced in a thin metal plate. It is difficult to analyze the eddy current by the ordinary BEM or FEM because the metal plate of the container is too thin. In this paper, we formulate the eddy current induced in the thin plate, and discuss adequacy and effectiveness of the equations in heating a plate with a conductive juncture installed for burning protection of the container.
