Probabilistic fatigue life prediction of notched components using strain energy density approach

To meet various functional requirements, engineering components are usually designed with geometrical discontinuities, which raise stress concentrations undergoing external loadings. Comparing with other locations, these regions with high levels of stress incline to initiate cracks under cyclic loadings, which determine fatigue strength of the whole part. Accordingly, a novel strain energy density-based model for notch fatigue life prediction is...
