ABSTRACT: Based on the existing
experiment results, the fretting fatigue contact geometry of a riveted two
aluminum specimen was studied using the finite element method. The contact
stress fields of the inner and outer contact edges on the two specimen’s up and down
surface under different contact friction coefficient and the fatigue loads were
analyzed, the influences
of the contact friction coefficient and remote stress on crack initiation were
discussed. The results were in well agreement with the observations of the
existing experiments, that is, the crack initiated places of the first aluminum
specimen change from the area of 900 to 450, and the crack initiated places of
the second aluminum specimen change from the area of 900 to 1350 with the
increase of the friction coefficient and the remote stress.
