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.ennon-destructive testing2D FEM modellinghardening depthincremental permeabilityhysteresis characteristics620658670conference paper
