Summary:
Fatigue cracks grown in compact tension specimens of 2024-T851 aluminum at ?K = 6.93 MN/m3/2 (R =0.1) were subjected to single-peak overloads of 17.31 MN/m3/2. After the overload, the specimens were held at zero load for periods of 3 min, 1 h, and 20 or more hours before recycling at ?K = 6.93 MN/m3/2. Increasing the rest time had the effect of slightly reducing the crack retardation as measured on the specimen surface
