Impact of Parameter Variation on Damage Tolerance Analysis Estimates
Abstract
This study was conducted to determine the effects of variations in damage tolerance analysis parameters on fatigue crack growth life. The damage tolerance analysis with variations in input parameters was performed at fatigue critical locations in two different aircraft types using probabilistic sensitivity analysis methods. Up to 12 input parameters. The geometry correction factors, stress spectrum scale factor and stress intensity factor values were found to affect the damage tolerance analysis estimates.
