“…The influence of mechanical strain caused by the stresses from external forces on the magnetic characteristics of soft magnetic materials is very important from both theoretical [1] and applied [2,3] points of view. In spite of the fact that these different physical 3D models of the influence of strain tensor on the relative magnetic permeability µ r tensor were presented previously [4,5], the generalized model of the influence of mechanical stresses on the magnetic characteristics of anisotropic materials was still not presented.…”

This paper presents a newly proposed domain wall energy-based model of the 2D strain dependence of relative magnetic permeability in highly grain-oriented anisotropic electrical steels. The model was verified utilizing grain-oriented M120-27s electrical steel sheet samples with magnetic characteristics measured by an automated experimental setup with a magnetic yoke. The model’s parameters, identified in the differential evolution-based optimization process, enable a better understanding of the interaction between stress-induced anisotropy and magnetocrystalline anisotropy in electrical steels. Moreover, the consequences of the simplified description of grain-oriented magnetocrystalline anisotropy are clearly visible, which opens up the possibility for further research to improve this description.
