Abstract
The concept of fatigue fracture entropy (FFE) is utilized and extended to predict and monitor the metal fatigue life of the specimens at different environmental temperatures via infrared technology. An application of the method via a real-time fatigue life monitoring unit is presented wherein, regardless of the environmental temperature, the unit automatically shuts down the machine prior to the onset of fatigue fracture. Results show that FFE is relatively constant for ambient temperatures from 25 °C to 200 °C. The analysis of the results also demonstrates that the variation of the plastic strain energy as a function of the number of cycles to failure can be generalized in a functional form independent of the environmental temperature.
