“…On the other hand, pure shear stress state induces highest anisotropy in the material. Even though different materials are studied, the modeled behavior under various mechanical loadings including biaxial ones and rotational magnetization is in agreement with the experimental measurements from [6] and modeling results from [3]. …”

A novel single sheet tester design is proposed and a directly coupled magneto-mechanical model is used to numerically analyze the behavior of iron sheets under biaxial magneto-mechanical loading applied by the tester device. Magneto-mechanically coupled constitutive equations of the material derived using an energy based approach are integrated into a finite element model of the single sheet tester device and simulations are performed to solve for the displacement field and the magnetic vector potential in the sample. The obtained numerical results of magnetostriction evolution due to uniaxial stress and stress induced anisotropies due to permeability variation under different magneto-mechanical loadings are presented. The simulation results are compared to the results published in the literature for the purpose of validation.

“…The model fits reasonably well and is able to predict the quadratic dependency of the magnetization curves on the stress, so that both compression and high tension reduce the permeability from the zero-stress case. This effect is not observed with the energy definitions of [3] and [7], although the effect can be taken into account with an additional correction term [8].…”

Modeling of Hysteresis Losses in Ferromagnetic Laminations Under Mechanical Stress

et al. 2016

View full text Add to dashboard Cite

A novel approach for predicting magnetic hysteresis loops and losses in ferromagnetic laminations under mechanical stress is presented. The model is based on combining a Helmholtz free energy -based anhysteretic magnetoelastic constitutive law to a vector Jiles-Atherton hysteresis model. This paper focuses only on unidirectional and parallel magnetic fields and stresses, albeit the model is developed in full 3-D configuration in order to account also for strains perpendicular to the loading direction. The model parameters are fitted to magnetization curve measurements under compressive and tensile stresses. Both the hysteresis loops and losses are modeled accurately for stresses ranging from -50 to 80 MPa.
