Life Prediction of Aluminum Alloy Structure Subjected to Corrosion Fatigue and Corrosion Damage

Abstract:

The strength of the aging structure deteriorates mainly as a result of corrosion and fatigue damage. In this paper, the life prediction methods of corroded and corrosion fatigued aluminum alloy structure were proposed. The stress multiplication of aluminum alloy structure subjected to corrosion damage was simulated by ANSYS software. We proposed the AFGROW software simulation method to predicate the numerical simulation of corrosion fatigue crack growth. At last, the life cycles of structures subjected to corrosion damage and corrosion fatigue were estimated, and a very good performance of the proposed methods are achieved after validation with the experimental data.
