Based on the fatigue crack growth results of the previous work for 2024-T351 aluminum alloy, the crack closure behavior under random loading was analyzed, and the correlation between the crack opening ratio and the stress ratio under random loading was discussed. The crack opening ratio under random loading can be expressed as a function of the stress ratio for the largest load cycle in a random load history. The correlation obtained is found to provide good predictions for crack growth under random loading.
