Effect of heat conduction on rapid evaluation of fatigue limit based on temperature evolution due to cyclic loading

The rapid evaluation technique of fatigue limit using infrared thermography has been developed during the past 30 years. In this technique, the fatigue limit is evaluated on the basis of the temperature evolution associated with cyclic loading. However, this technique is still not reliable enough be...
