Abstract:

Five computational models based on Coffin-Manson rule are presented to predict corrosion fatigue life in low cycle regime. Fatigue test data of seven engineering alloys in air and corrosive environments are fitted to these models.The fitting results, the accuracy of the models and the scope of their applications are discussed.

Key words: fatigue life, corrosive environment, model, fit
