Microscopic study of 5083-H321 aluminium alloy under fretting fatigue condition [PDF]
, 2011 Fretting occurs where there is small amplitude oscillating motion between solid surfaces in contact. With even small loads or prolonged operation, fretting may lead to crack initiation followed by fretting fatigue.

Equivalent configurations for notch and fretting fatigue [PDF]
Fracture and Structural Integrity, 2015 Under the typical partial slip conditions under which fretting fatigue takes place, the amount of superficial damage is small. Therefore, the substantial reduction in fatigue life caused by fretting, when compared to plain fatigue, may well be more ...

Fretting Fatigue in Mechanical Joints: A Literature Review
Lubricants, 2022 Fretting fatigue is a fatigue damage process that occurs when two surfaces in contact with each other are subjected to relative micro-slip, causing a reduced fatigue life with respect to the plain fatigue case.
