A model for high cycle fatigue

Engineering Fracture Mechanics, 1992
Abstract Failure due to fatigue consists of such macroscopic events as crack initiation and propagation. Microscopic events including microcrack nucleation, microcrack growth and coalescence of some of the microcracks are also important in that such crack interactions can be considered to contribute to the development of a critical defect, i.e.

Very high cycle fatigue measuring techniques

International Journal of Fatigue, 2014
Abstract Ever since high-strength steels were found to fail below the traditional fatigue limit when loaded with more than 108 cycles, the investigation of metals’ and alloys’ very high cycle fatigue properties has received increased attention. A lot of research was invested in developing methods and machinery to reduce testing times.

Small Cracks and High-Cycle Fatigue

Aerospace, 1996
Abstract The problem of high-cycle fatigue (HCF) failures that has recently plagued the aircraft jet-engine industry is associated with the rapid growth of small defects under the action of high-frequency vibrational or resonant loading; such defects have been associated with regions of microstructural damage attributed to such processes

Notch Effect in High Cycle Fatigue

2001
This paper presents a different approach for the estimation of fatigue life duration of notched shafts. The traditional approach, which is based on the notch radius and the stress concentration factor, is not applicable for all stress concentration geometries, for example shafts with key-seats.

High-cycle fatigue / low-cycle fatigue interactions in Ti-6Al-4V

2014
The largest single cause of failure in fan and compressor components in the cold frontal sections of commercial and military gas turbine engines has been attributed to high cycle fatigue (HCF). Additionally, both high-cycle fatigue (HCF) and lowcycle fatigue (LCF) loadings are widely recognized as unavoidable during operation of these components and ...
