Prediction on fatigue limit of notches with non-propagating crack

Prediction on fatigue limit of notches with non-propagating crack

Theoretical estimation of fatigue limit of notches under axial push-pull loading was made with an emphasis on the formation of non-propagating crack. A critical notch radius and a critical stress concentration factor were determined so as to distinguish notch fatigue limits with crack initiation and...

Beschreibung
Zusammenfassung:Theoretical estimation of fatigue limit of notches under axial push-pull loading was made with an emphasis on the formation of non-propagating crack. A critical notch radius and a critical stress concentration factor were determined so as to distinguish notch fatigue limits with crack initiation and crack non-propagation. Errors in calculating fatigue limit of notches and comparisons between theoretical and experimental results were discussed.
