Fatigue Life Evaluation of Unstiffined Aluminum Panels with Multiple Site Damage

Abstract:

Fatigue test were performed on 2024-T62 aluminum panels with MSD cracks, and the fatigue behavior of panels with MSD was analyzed. By the experiment results, the speed of crack growth increased stably in most time of life span, and crack growth rate curves were plotted. Then a rough method was presented to evaluate fatigue life of aluminum panels based a constant geometric factor from the curves and the evaluation is useful in engeering.
