A simplified multiscale approach and a Helmholtz energy based approach for modelling the multiaxial stress dependent magnetic hysteresis behavior of electrical steel sheets are compared. The models are identified from uniaxial magneto-mechanical measurements. Both approaches model the hysteresis losses under multiaxial stresses with reasonable accuracy compared to the measurements.
