WebOct 1, 2006 · The physical phenomenon known as fretting fatigue is observed in several types of practical applications, such as: threaded pipe connections [1], bolted/riveted joints [2], blade-disk... Webslippage during fretting of the joint interface is the major source of frictional energy loss and, hence, damping associated with joints. It is common to report the stiffness and damping of the jointed interface by obtaining fretting responses from an apparatus, simultaneously imposing constant normal and oscillatory tangential loads. Fretting ...

Fretting - Wikipedia
WebApr 4, 2011 · Fretting wear is defined as the damage of tribo-surfaces, induced by small amplitude oscillatory displacements [1]. Fretting wear can occur in combination with oxidation, adhesion, surface fatigue and abrasion [2]. WebJul 1, 2002 · Bolt connection plays an important role in assembly structures. Under long-term vibrations, bolted joint interface will change due to fretting-induced friction and wear behavior. This leads to changes in the dynamic characteristics of assembly structures, which increases the difficulty of control of the structure.
