Abstract :
We present a new approach for identification of the material electromagnetic parameters that are involved in electrothermal process simulations. We use inverse analysis techniques coupled with an induction heating finite-element model (FEM) and software developed in our laboratory. We describe here the direct induction heating FEM, the physical formulations, and the iterative identification procedure, and then present numerical tests and results.
