Probabilistic fatigue modeling of notched components under size effect using modified energy field intensity approach

Fatigue assessment in the presence of intricate geometries is critical for ensuring structural integrity and reliability of engineering components. Based on the energy field intensity (EFI) approach, this study establishes a probabilistic framework to predict fatigue life of notch components considering size effect. Specially, a new concept of effective damage zone (EDZ) is introduced based on characteristic total strain energy density (TSED),...
