Fatigue and Corrosion Fatigue of HY-80 Steel, as Applicable to Anchor Bolt Failures.
Abstract
The fatigue crack growth rate behavior of compact tension specimens of HY-80 steel have been determined for low stress intensity ranges. Tests were performed in laboratory air and sea water, both freely corroding and cathodically polarized to -0.85 volts (cu-CuSO4), and at stress ratios, R, of 0.1 and 0.8. For the lowest stress intensity ranges investigated apparent thresholds for tests in air were less than in sea water at both stress ratios. Comparison of the present results with those upon other steels of various strength levels suggests that improved fatigue crack growth resistance should result from selection of HY-80 for low stress intensity range, high mean stress intensity applications.
