A magneto-elastic vector-play model under rotating fields and multiaxial stress states

The hysteresis behavior of ferromagnetic materials under stress is represented using an energy-based vector-play approach combined with a multiscale model. A mathematical adaption of the pinning parameter allows capturing the vanishing of hysteresis losses under a rotating field near saturation. Using parameters identified from uniaxial measurements only, the modeling results agree well with the measured hysteresis loops under multiaxial mechanical loadings and rotating fields. The hysteresis loss trend under stress is also reproduced with the proposed approach.
