Micromagnetic model for the influence of biaxial stress on hysteretic magnetic properties

A micromagnetic model involving deviatoric normal stress factors and Schneider-Cannell-Watts model evaluates the effect of biaxial stress on the hysteretic and magnetoelastic properties in polycrystalline-composed steel structures. Computer and experimental results are consistent with the kind of magnetic changes induced by the stress. Different biaxial stresses are determined nondestructively by the new model.
