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

High Cycle Fatigue in the Transmission Electron Microscope
Nano Letters, 2016 One of the most common causes of structural failure in metals is fatigue induced by cyclic loading. Historically, microstructure-level analysis of fatigue cracks has primarily been performed post mortem. However, such investigations do not directly reveal the internal structural processes at work near micro- and nanoscale fatigue cracks and thus do not

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.

Fatigue Properties of Long-Term Thermally Aged Low-Alloy Steel
MetalsFatigue properties of low-alloy steels, LAS, are well defined in air and at the beginning of life. However, the potential influence from thermal ageing under conditions relevant for the nuclear industry is uncertain. In this study, the fatigue properties
