High-Temperature Low Cycle Fatigue Life Prediction and Experimental Research of Pre-Tightened Bolts
Metals, 2018 Bolted connections are widely used in various mechanical structures due to their superior fastening properties. However, vibration and fatigue loads in the structure are likely to cause fatigue failure of the bolted joints, especially those under high ...

High Cycle Fatigue Behaviour of Functional Spinal Units
INDUSTRIAL HEALTH, 2010 Vibrations have been shown to be an important risk factor for spinal pathologies. The underlying mechanisms are poorly understood and in vivo data scarce and difficult to obtain. Consequently numerical models are used to estimate spinal loading; requiring fatigue strength information, which was obtained in this study for spinal specimens from young and

MODELLING OF STRESS GRADIENT EFFECT ON FATIGUE LIFE USING WEIBULL BASED DISTRIBUTION FUNCTION [PDF]
, 2013 In the present paper, a new approach is developed in order to take into account the stress gradient effect on fatigue life of structural components. The proposed approach is based on the weakest link concept in which the shape coefficient of the Weibull ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

RESEARCH OF HCF/LCF COMBINED CYCLE FATIGUE EXPERIMENTAL TECHNIQUE FOR BLADE
Jixie qiangdu, 2020 To verify the fatigue life under high-low cycle combined loads of the blade the combined fatigue experimental technique was established. The orthogonal loads decoupling method was proposed based on the cylindrical rolled bearing and linear slide rail,and

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
