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.
