Abstract

A complete 2-D finite-element modeling for ferromagnetic materials is described. It is based on the definition of an adapted constitutive law which has to be completed by an hysteresis model like Preisach´s one. A representation of the irreversible part of the ferromagnetic behavior by equivalent currents is given; a classical nonlinear system must be solved finally. Some numerical results are presented to underline the physical capacities of the method. Quantities like remanent induction and demagnetizing field can be calculated by this method
