Abstract

A modified Trantina-Johnson model was developed to characterize corrosion fatigue crack growth behavior. Crack growth accumulative methodology based on the Willenborg-Chang rule was used to evaluate the residual lifetimes of corrosion fatigue crack growth. Fatigue crack growth tests were performed on 2524-T3 and 7050-T7451 aluminum alloys subjected to constant amplitude and random spectra loading under the environments of dry air and 3.5% NaCl sodium chloride solution, and the load-environment interaction and load interaction mechanisms were deduced from fractographic analysis. The developed models showed good correlation with experimental results.
