Notes:
The influence of environmental corrosion on fatigue life of 2024-T3 aluminum alloy isinvestigated in this paper. Experiments with center-hole specimens and CC(T) specimens areconducted and reported. The test result shows that the corrosion influence is becoming seriouswhile the environmental causticity is increasing, and the influence on crack initiation life is greaterthan that on crack propagation life. Analysis of the test data also indicates that the environmentalcausticity enlarges the dispersivity of fatigue life. Using the corrosion-modification-factor obtainedby eigenvalue or mean value to prediction the fatigue life with high reliability will cause anunconservative conclusion
