Fretting Fatigue in Mechanical Joints: A Literature Review

Fretting fatigue is a damage process that occurs when two surfaces in contact with each other are subjected to relative micro-slip, causing reduced life respect the plain case. has now been studied deeply for over 50 years, but still no univocal design approach universally accepted. This review presents literature study involves three main types of mechanical joint affected by fretting (press-fitted shaft hub joints, dovetail and bolted joints) aiming at giving insight into progress made terms guidelines engineers.
