A Theoretical Characterization of the Coupling Effects of Frequency and Mechanical Stresses on the Magnetic Properties of the Ferromagnetic Material

摘要

The topic of the paper is to model simultaneously, the effect of frequency coupled with applied mechanical stresses, on the magnetic hysteresis of ferromagnetic sheets. The magneto-mechanical model to be exploited is deduced from the classical effective field intended by Sablik-Jiles-Atherthon (S.J.A.). The previous relationship has been adjusted by introducing the parameter which takes into account the internal reaction of the material subjected to external mechanical stress. The corresponding phenomenon is not considering in literature, it will be noted stress demagnetizing field. Different magnetic characteristics are plotted by applying the proposed model. Thus, the model is validated through extensive simulations and compared with ones obtained experimentally in literature. A reasonable trend has been reached.
