Anisotropic magnetic hysteresis modeling with four material hysteresis parameters

This work proposes a new vectorial magnetic hysteresis model that accounts for the anisotropy of materials. It extends an isotropic hysteresis model by modeling anhysteretic phenomena using a multi-scale approach. Hysteresis, on the other hand, is treated macroscopically. This paper provides a procedure for identifying the set of material constants. The model has been tested on a GO Fe-3%Si alloy and is capable of reproducing magnetic behavior for both fixed and rotating magnetization direction. The proposed formalism allows introducing multi-physics couplings without any particular difficulty.
