Fatigue tests have been carried out on aluminum alloy lugs with different hole diameters (d = 10 mm and d = 30 mm) and configurations (Kt = 3.2 and kT = 3.7). A strong improvement in fatigue properties was observed in cases of relative interference fits larger than 0.2 %. The effect of the stresses produced by the interference fit were theoretically analyzed and the critical stress level, below which the interference fit has a beneficial effect, was determined. A method for evaluation of the fatigue life of interference-fit aluminum lugs is proposed. (Biller)
