Electromagnetic examination of hardened depth of steel using 2D nonlinear hysteresis FEM analysis

The inspection of the hardened depth on surface carbon hardening steel is an important quality parameter inmaintenance and for the other applications as well. For this purpose, two kinds of samples with differenthardening depth are studied. The flux density in the surface hardening steel is examined using 2D finite elementcode taking into account the hysteretic and eddy current behaviour. The simulation results are compared toExperimental signals.
