A hybrid Jiles-Atherton/Armstrong magnetization model considering uniaxial anisotropy for magnetostrictive alloy rods
Source abstract
Abstract
A magnetization model for magnetostrictive alloy (Galfenol) rods with uniaxial anisotropy is established, based on the theory of the Jiles-Atherton model and the Armstrong model. The magnetization under different magnetic fields and applied stresses at different directions has been calculated by the constitutive model. The magnetic properties of a Galfenol rod were made and are consistent with the calculated results. The proposed model accurately describes the relationship between the magnetization and applied magnetic field under different stresses for Galfenol rods, in particular, and can be applied to general ferromagnetic materials with uniaxial anisotropy due to crystallography or shape.
