ON SOME PARTICULARITIES OF FRETTING FATIGUE (I)
Fretting is a process which invariably occurs on contracting surfaces
of tightly metal joints subjected to vibrational 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 phenomena. The aircraft industry is perhaps one of the
most affected by the fretting fatigue problem.
