Probabilistic analysis and Uncertainty Quantification for F&DT

F&DT analysis has traditionally been done with deterministic analysis and conservative scatter factors. In an attempt to move towards risk informed strategy, advanced probabilistic approaches should be developed. Need to develop computational methods for quantifying and managing the impact of various uncertainties (e.g., material properties variability, load to stress variability, manufacturing tolerances, etc.,) on the fatigue and damage tolerance assessment of airframe structures.
