Journal of Marine Science and Engineering, 2022 The subsea wellhead (SW) system is a crucial connection between blowout preventors (BOPs) and subsea oil and gas wells. Excited by cyclical fatigue dynamic loadings, the SW is prone to fatigue failure, which would lead to the loss of well integrity and ...

Fatigue damage model of woven glass-epoxy fabric composite materials
Journal of Materials Research and Technology, 2020 Based on the Stiffness degradation rule of woven glass fiber composite under fatigue loading, a phenomenological fatigue damage model containing two material parameters in which first is directly proportional to the fatigue life and second is inversely ...

Fatigue damage in composite cylinders
Polymer Composites, 2009 AbstractIn this study, optimal angle‐ply orientation of symmetric composite cylinders under fatigue loading is investigated. The fiber‐reinforced plastic cylinders were manufactured from E‐glass/epoxy. The layers were manufactured symmetrically in [±75°]2, [±60°]2, [±55°]2, and [±45°]2 orientations.

Subrupture tendon fatigue damage [PDF]
Journal of Orthopaedic Research, 2008 AbstractThe mechanical and microstructural bases of tendon fatigue, by which damage accumulates and contributes to degradation, are poorly understood. To investigate the tendon fatigue process, rat flexor digitorum longus tendons were cyclically loaded (1–16 N) until reaching one of three levels of fatigue damage, defined as peak clamp‐to‐clamp strain ...

Modelling the role of non metallic inclusions on the anisotropic fatigue behaviour of forged steel [PDF]
, 2011 Forged components are known to show high cyclic and monotonic mechanical properties. This is mainly due to a better compactness and a finer microstructure introduced by the forming process. However, this good mechanical behaviour is sometimes a source of
