Identification of the ferromagnetic hysteresis simulation parameters using classic non-destructive testing equipment

Electromagnetic non-destructive controls are performed daily by steel manufacturers and user companies. Many methods exist, including Eddy Current Testing (ECT), Magnetic Particle Inspection (MPI), Incremental Permeability (MIP), Barkhausen noise (MBN) … In this domain, progresses constant, however there limitations accurate simulation tools able to improve the efficiency still expected. Most of steels ferromagnetic characterized a strong nonlinear hysteretic magnetic behavior. A precise taken into account hysteresis is mandatory in development useful tools. The standard characterization imposes restrictive conditions (geometrical, electrical …) most Non-Destructive (NDT) industrial end-users face difficulties obtain these inevitable experimental results. manuscript, we describe an alternative method adjust parameters based on results coming from classic NDT equipment. acquisition flat coil impedance ECT configuration under superimposition quasi-static excitation (MPI equipment) plot tested specimen MIP signature. Dodd & Deeds (D&D) analytical solution for used return corresponding permeability. An optimization process modified Jiles-Atherton (J-A) model run extract suitable combination parameters. Finally, good comparison with B(H) worth as validation method.
