| Objective To study the evaluation method of fatigue life of pre-corroded aluminum alloy. Methods By means of damage mechanics, a theoretical model for fatigue life prediction of pre-corroded parts was established, and precorrosion fatigue experiment was conducted on LY12CZ aluminum alloy to verify the accuracy of the proposed model. Results Experimental results of the fatigue life of pre-corroded aluminum alloy parts were in good agreement with the predictions of the proposed model established based on damage mechanics. Conclusion The proposed model based on damage mechanics was reasonable and effective in predicting the fatigue life of pre-corroded aluminum alloy. |
