Keywords: Generalized local strain approach; Thickness effect; Stress state; Fatigue life

A generalized local strain approach is presented to calculate thickness influence in fatigue life assessment of structural components. Validations against calculations and fatigue test results indicate that the generalized local strain approach can be applied to predict fatigue life of specimens under three-dimensional stress constraints effectively.
