Rapid determination of fatigue failure based on temperature evolution: Fully reversed bending load
M. Amiri,Michael M. Khonsari +1 more
TL;DR: In this article, an experimental and theoretical study is carried out to investigate the temperature evolution of Aluminum 6061 and Stainless Steel 304 specimens under cyclic fatigue load, and it is shown that the slope of the temperature plotted as a function of time at the beginning of the test can be effectively utilized as an index for fatigue life prediction, thereby saving testing time.

Study of thermal effects associated with crack propagation during very high cycle fatigue tests
TL;DR: In this paper, the thermal effects associated with the propagation of a fatigue crack in a gigacycle fatigue regime were studied. But the authors focused on the time evolution of the temperature fields in specimens and showed a good correlation with experiment and provided experimental proof that the propagation stage constitutes a small part of the lifetime of the specimen.

Fatigue limit evaluation of metals using an infrared thermographic technique
TL;DR: In this paper, the authors illustrate three advantages of infrared thermography as a non-destructive, real-time and non-contact technique, which allows first observation of the physical processes of damage and failure in metals, and in particular, automotive components subjected to fatigue loading, second detection of the occurrence of intrinsic dissipation, and third evaluation of the fatigue strength in a very short time.
