On Understanding Environment Enhanced Fatigue Crack Growth. A Perspective View (1968-1977).

Abstract

Corrosion fatigue (CF) is a generic term that is used to describe the phenomenon of cracking (including environment enhanced fatigue crack growth) in materials under the conjoint actions of an applied cyclic stress and a corrosive (aggressive) environment. It has been recognized as an important cause for failure of engineering structures. Characterization and understanding of corrosion fatigue are essential to service life prediction, fracture control, and the development of fatigue resistant alloys. Quantitative characterization and understanding have been hampered by the complexity of the problem, difficulties in separating the effects associated with crack initiation and with crack growth, and the absence of truly interdisciplinary attack of this problem.
