Safety cuts (or confidence cuts) are used in the repair of fatigue damaged fastener holes in aircraft structure to ensure that any residual crack is removed in the repair process. The necessity of using safety cuts was investigated by growing cracks

Specimens of Al 7175-T7452 and Al 7075-T6511 were fatigue tested under several spectra to obtain estimates of the standard deviation of the log of the fatigue life and to determine if there was bimodality as was found for Al 7050-T7451. The 7175 allo

This work examines the effect of dynamic buffet loads (small cycles) on the scatter in the fatigue life of aircraft aluminum. Current life cycle management of fighter airframes assumes, without engineering evidence, that buffet loads cause an increas

The effect of variable amplitude loading on the fatigue life and failure mode of adhesively bonded double strap (DS) joints made from clad and bare 2024-T3 aluminum was investigated. Under constant amplitude loading, the clad specimens failed through

The effect of warm water treatment on the fatigue life of 2024 T3 aluminum alloy adhesively bonded with FM73 epoxy adhesive was investigated. As expected, the fatigue life was shown to depend on the surface preparation of the bonds. Fatiguing the spe

The fatigue life of epoxy-bonded, single-lap shear joints was investigated as a function of surface preparation both with and without a silane pretreatment, under both dry and wet conditions. The effect of R-ratio was also investigated. The results s
