Dynamic hysteresis lump model including fractional operators for the incremental permeability nondestructive testing
Résumé
Magnetic Incremental Permeability (MIP), represents the effective permeability for a small alternating field superimposed on a larger steady field. A dynamic lump scalar hysteresis model including fractional operator is proposed here to model MIP. The model considers both tangent excitation field H and permanent mechanical stress T as excitation of the material. Numerical results and simulation parameters (fractional order) allow to clarify the MIP mechanisms and to define degradation threshold level for industrial applications.
