A Study on the Fatigue Life Prediction of Al-2024 with Corrosion

In this study, test results for fatigue crack propagation of Al-2024-T3511 are presented considering corrosion effects, and fatigue lifes are compared for the cases of corrosion and non-corrosion. Higher corrosion environments show lower fatigue life and faster crack growth. To predict the corrosion fatigue life, a corrosion factor concept is newly introduced and applied in Paris` law. The predicted results show good agreement with experimental data and this corrosion fatigue model can be successfully used for the prediction of fatigue life of aluminum structure with corrosion effects. ᜎࠀ㘲㐮㄰㔻Ԁ䭃䑎䷕੿6〰㬅K䍄乍쀗ᘍ ܀㘲㐮ㄷ㬅K䍄乍ꠗᘍ頀܀㘲ㄮ㌸㬅K䍄乍
