Fatigue crack growth rate experiments per ASTM E647 were performed on compact tension specimens of high strength low alloy structural steel (HSLA80, ASTM A710, base plate and HAZ region) in 3.5% NaCl, and artificial seawater solutions. The objective of the research was to investigate corrosion effects on crack growth rates, and threshold stress intensity factor range. Stress ratios for the tests were 0.1, and 0.8 while a cyclic loading was applied at a test frequency of 1. Comparison of the ...
