Abstract
The effects of stress ratio (R) and crack-opening behavior on fatigue crack growth rates (da/dN) for Aluminum Alloy (AA) 2024-T3 were studied using constant-ΔK testing, closure measurements, and fractography. Fatigue crack growth rates were obtained for a range of ΔK and stress ratios. Results show that constant ΔK fatigue crack growth for R ranging from near 0 to near 1 is divided into three regions: Region I where R is low, Region II where R is intermediate, and Region III where R is high.
