Variable-amplitude fat@ue studies of 2024-13 ab&num alloy were performed to examine the effect of sheet thickness on fatigue crack growth rate retardation. Results indicated tbat the amouot of retardation increased with decreasing specimen thickness. This phenomenon was attrii to enhanced plastic st
It is well accepted that the steady-state fatigue crack growth rates of long cracks depend uniquely on AK for a fixed load ratio R and test environment. Anomalous growth behavior of short cracks in either inert or deleterious environments that has been reported [1-7], however, calls into question th
