Local Measurement of Peening-Induced Residual Stresses on Iron Nickel Material Using Needle Probes Technique

Résumé

Mechanical characterization of electrical steels in an attempt to predict component fatigue has drawn more and more attention to magneto-mechanical coupling in ferromagnetic materials. In this paper, experimental evidence on the magneto-mechanical coupling of a thin Fe-Ni50 sheet subject to multiaxial stress due to electromagnetic peening-induced residual stresses is presented. A comprehensive model of the stress-dependent magnetostriction is validated using the Jiles-Atherton-Sablik (JAS) model for scalar ferromagnetic hysteresis. The JAS parameters are determined from an optimization algorithm, and the dependence of the model accuracy regarding its own parametrization is analyzed. Good correlation of experimentation data with the JAS model was obtained upon careful optimization of the model parameters.
