International audience ; The fretting-fatigue behaviour of shrink fit lug-bush assemblies is investigated. In this paper, experimental fatiguetests are carried out on lug-bush specimens with three different levels of interference fit. It is observed thatthe relative movements of fretting induce tribo-oxidation phenomena at the shrink-fit interface and that the crackinitiation sites correspond well to the oxides formation spots. The increase in the fatigue life with interference fitis consistent with stress analysis considering the SWT multiaxial fatigue criterion, but the predicted fatigue life isnot conservative relative to material reference data. In order to account for fretting surface damage, differentapproaches are investigated considering homogeneous and heterogeneous distributions of the coefficient offriction.
