摘要：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
