ON SOME PARTICULARITIES OF FRETTING FATIGUE (II)
Fretting is a process which invariably occurs on contracting surfaces of
tightly metal joints subjected to vibration loading. The superficial damage caused
by the rubbing of the contacting surfaces together with the severe stress gradient
under the contact region accelerate the nucleation and early growth of cracks
witch can lead to catastrophic failure of there is a least one of the components of
the fitting subjected to a remote fatigue load. This is the so called fretting fatigue
phenomenal. The aircraft industry is per hops one of the most affected by the
fretting fatigue problem.
