Analytical Model for External Induction Variations of a Ferromagnetic Cylinder Undergoing High Mechanical Stresses in a Low Magnetic Field of Any Orientation

Inverse Problem Approach to Characterize and Model Magnetization Changes in a Thin Shell Structure Undergoing Magneto-Mechanical Effects

“…An analytical solution to Jiles Law of Approach [2] was also successfully found to accurately model the evolution of external with stress, in the case of a vertical inductor field [1]. This dual approach has been recently generalized to any field direction, when stress and field are no more parallel [3].…”

“…In the paper, the experimental setup and the method of inversion are presented. Using results derived in [3], a direct vectorial model for the variations of magnetization with pressure is introduced. The magnetization resulting from this model is used to predict the magnetic induction signature which would…”

Inverse problem approach to characterize and model magnetization changes in a thin shell structure undergoing magneto-mechanical effects

“…In the paper, the experimental setup and the method of inversion are presented. Using results derived in [3], a direct vectorial model for the variations of magnetization with pressure is introduced. The magnetization resulting from this model is used to predict the magnetic induction signature which would Manuscript be measured by a tri-axial sensor.…”

“…The magnetization law for any inductor field can be reconstructed using (1), by linear combination of (3) and (4). In addition, being an intrinsic parameter of the material, its fitted value found in [3] was reused for the law in magnetization. Hence, the analytical law for the transverse component of magnetization should be expressible as…”

Stress Monitoring in Steel Elements via Detection of AC Magnetic Permeability Changes

“…The source of magnetostriction is strain dependence of magneto-crystalline anisotropy originating from the spin-orbital coupling of electrons. The variety of magneto-mechanical effects in bulk material and thin films was reported both in historical papers [2,3] and in more recent ones [4][5][6][7][8][9]. These phenomena can be utilized for determining magnetoelastic parameters of materials [8] as well as for nondestructive evaluation (NDE) of mechanical elements [7].…”
