Journal:IEEE SENSORS JOURNAL

Abstract:Cyclic loading can lead to fatigue damage on the
surface or subsurface of a gear tooth. In order to evaluate the
contact fatigue damage, this paper applies eddy current pulsed
thermography (ECPT) for fatigue damage characterization at
different intervals of the loading cycle. The challenging task of
fatigue evaluation is one of solving the qualitative microstructure
state characterization before microcrack initiation. This paper
proposes the thermooptical flow entropy tracking method to
trace the heat flow and characterize the degree of fatigue
damage
