... either a deterministic or probabilistic framework. Fatigue is perhaps the most widely encountered damage mechanism ( Ref 18 ), and two major design philosophies have been employed: safe-life (based on either stress versus life-cycle or strain versus life-cycle curves, Ref 19 ) and damage tolerant (based...

... (HCF) or plastic strain-based criteria for low-cycle fatigue (LCF) have been applied based on transfer of results from tests on relatively small-scale unnotched laboratory specimens to structural components ( Ref 1 ) to estimate crack initiation life. Similarly, test results for crack propagation in...
