ABSTRACT = {This paper presents a thermodynamic characterization method for estimating the internal crack growth 
rate, which has been a puzzle in very high cycle fatigue research. A theoretical approach of surface 
temperature is established with crack size, initiation site, and time for thin sheet material. Infrared 
thermography is used to study the inner crack behavior and the heat dissipation phenomenon under 20 kHz 
vibration loading on high-strength stainless steel. A numerical simulation reveals the consequent 
temperature elevation on the surfaces by the heat generation at the crack tip and the heat conduction. 
Ultimately, the internal crack growth rate and final fatigue failure prediction are obtained by combining the 
calculation of heat dissipation and the observed evolution of the surface temperature field.},
