Abstract
This effort will develop probabilistic micromechanical fatigue life modeling software . The model will integrate material characterization information with turbine engine structural design methods in order to predict the scatter in the fatigue strength ofa component subjected to high cycle fatigue (HCF). Proven feasible in Phase I, the Phase II will extend our analysis from a simple specimen to include FOD, LCF/HCF interaction, and surface treatment. Ti-6Al-4v and Ti-17 materials will be evaluated from a
