Magnetomechanical coupling is introduced in the assembled domain structure model, which is an energy-based multiscale magnetization model. The magnetoelastic interaction between mesoscopic particles was taken into account. The magnetization processes of grain-oriented and non-oriented steel were simulated. Magnetization curves in the rolling and transverse directions of a grain-oriented electrical steel were reconstructed. The degradation of non-oriented electrical steel by an external stress is also represented.
