Summary: | The aim of this paper is the modeling of the stress demagnetization effect on
the magnetic properties in a non-oriented Fe-Si 3% sheet under different
external stresses. The magneto-mechanical model used for magnetic hysteresis
is based on a model originally formulated by Sablik-Jiles-Atherthon (S.J.A.).
This latter has been modified by including both the stress demagnetization
factor and the eddy current effects. The influence of the stress
demagnetization term SDT on the magnetostrictive behavior of the material is
also modeled. The proposed model has been validated by extensive simulations
at different stresses, namely compressive and tensile stresses. Simulation
results obtained by this model are very close to those published in the
literature. Using the proposed model, very satisfactory performance has been
achieved.
