Boundaries for increasing the fatigue limit of the bearing steel SAE 52100 by thermomechanical treatments [PDF]

open access: yes, 2011
High end applications often require high strength materials especially regarding the fatigue limit. It is still an open question what the highest fatigue limits are and how to increase them further in high strength steels.

Effect of expiratory muscle fatigue on exercise tolerance and locomotor muscle fatigue in healthy humans [PDF]

open access: yes, 1988
High-intensity exercise (> or =90% of maximal O(2) uptake) sustained to the limit of tolerance elicits expiratory muscle fatigue (EMF). We asked whether prior EMF affects subsequent exercise tolerance.

A study on rapid evaluation of fatigue limit based on temperature variation (Source of the second harmonic of temperature variation)

open access: yesNihon Kikai Gakkai ronbunshu, 2018
The technique of rapid evaluation of fatigue limit using infrared thermography 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 structures.
