Inverse Problem Approach to Characterize and Model Magnetization Changes in a Thin Shell Structure Undergoing Magneto-Mechanical Effects
Résumé
Direct measurement of magnetization M inside a complex ferromagnetic geometry is generally impossible. In this paper, we propose to use an inverse problem algorithm to determine the law of variation of M for such structures, accounting for the magneto-mechanical effects it is undergoing. The analytical law obtained leads to an intrinsic characterization model of magnetostriction inside the structure. Validation of the approach is achieved on a prototype undergoing high mechanical stresses in low magnetic field, by comparison with the predicted magnetic signature in the vicinity of the prototype, and measurements performed on external magnetic sensors.
