Critical length parameter of HDPE and its use in fatigue lifetime predictions
Fracture and Structural IntegrityThe contribution describes the fatigue lifetime predictions of polyethylene notched specimens based on the theory of critical distance. The approach uses the line method, which averages the axial stress over the critical distance.

Probabilistic temporal extrapolation of fatigue damage of offshore wind turbine substructures based on strain measurements [PDF]
Wind Energy Science, 2022 Substructures of offshore wind turbines are becoming older and beginning to reach their design lifetimes. Hence, lifetime extensions for offshore wind turbines are becoming not only an interesting research topic but also a relevant option for industry ...

Taking into account the non-proportional loading effect on high cycle fatigue life predictions obtained by invariant-based approaches [PDF]
MATEC Web of Conferences, 2019 Industrial structures are often subjected to multiaxial fatigue loadings. If the multiple stress signals are not synced the loading is said to be non-proportional.

Fatigue in the core of aluminum honeycomb panels: Lifetime prediction compared with fatigue tests [PDF]
International Journal of Damage Mechanics, 2013 In comparison to their weight, honeycomb composite structures have a high bending stiffness, which makes them very suited for every application such as airplanes, railway-cars and vehicles, where little weight is important. The sandwich panels consist of two thin and stiff aluminum face sheets, which are bonded to a thick and lightweight aluminum ...

Machine learning-based fatigue lifetime prediction of structural steels
Alexandria Engineering JournalFatigue of materials stands as a prevalent cause of mechanical structure failures, which often occur suddenly, unpredictably, and catastrophically. Accurately predicting the fatigue lifespan of materials is crucial, especially given the potential for ...
