Rapid evaluation of fatigue limit using infrared thermography: comparison between two methods for quantifying temperature evolution

The technique of rapid evaluation of fatigue limit using infrared thermography was developed and has been paid attention during the past 30 years. This technique is beneficial because it also makes possible to detect the location of fatigue damage in real products. In the thermographic technique, th...

description	The technique of rapid evaluation of fatigue limit using infrared thermography was developed and has been paid attention during the past 30 years. This technique is beneficial because it also makes possible to detect the location of fatigue damage in real products. In the thermographic technique, the fatigue limit is determined based on the temperature evolution with the load amplitude. In this research, two methods for quantifying the temperature evolution from measured temperature variation (mean temperature rise and second harmonic amplitude) as well as two types of infrared camera (quantum and thermal type) are compared with each other in order to assess the applicability of the thermographic technique. Experiments are conducted for double edge notched specimens of type 304 stainless steel.
