Energy field intensity approach for notch fatigue analysis
Source abstract
Abstract
Abstract Notched components with complex configurations are normally designed for engineering functional requirements. Geometrical discontinuities generally result into stress concentration and multiaxial stress states and eventually lead to fatigue failure. However, highly efficient methods for notch fatigue analysis of engineering components are still lacking. In this regard, by combining energy criteria with FE simulations, a new concept of energy field intensity (EFI) is proposed and an EFI-based framework is established for notch fatigue analysis of engineering components under multiaxial stress states. Better correlation of model predictions with experimental results of GH4169 and Al 7050-T7451 alloys are provided by the proposed model rather than that by Fatemi-Socie, Sun-Shang and energy criteria.
