Effects of electroplated zinc-nickel alloy coatings on the fatigue strength of AISI 4340 high strength steel
(2005-12-01)
It is well known that fatigue behaviour is an important parameter to be considered in mechanical components subjected to constant and variable amplitude loadings. In combination with corrosion phenomenon, fatigue effects ...
Estimation of notch sensitivity and size effect on fatigue resistance
(Elsevier, 2013-12)
This paper addresses the problem of high cycle fatigue resistance associated to notches and the role of short crack propagation in the fatigue notch sensitivity quantified by the notch factor. An integrated fracture mechanics ...
Analysis of the influence of defects on fatigue resistance of metallic components
(EDP Sciences, 2014-06-09)
The influence of defect on fatigue resistance of components is carried out by using a propagation threshold approach to estimate the high cycle fatigue resistance of components from data of intrinsic properties of the ...
Fatigue behaviour study on repaired aramid fiber/epoxy composites
(2009-07-01)
Aramid fiber reinforced polymer composites have been used in a wide variety of applications, such as aerospace, marine, sporting equipment and in the defense sector, due to their outstanding properties at low density. The ...

A fatigue life estimative method based on dynamic mechanical and fatigue analyses
(2020-09-01)
In this study, a model of fatigue life estimative based on dynamic mechanical analysis and fatigue tests is validated. Storage modulus is the viscoelastic parameter which better correlate with fatigue resistance. Accordingly, ...
An investigation of electrolytic surface damages and electroplated crhomium effects on fatigue behavior of high strength steel
(2001-12-01)
Fatigue crack initiation occurs at the surface, although sub surface nucleation has also been reported. Localized imperfections like inclusions close to surface and surface small pits can result in crack sources. Coatings ...

FATIGUE PROPERTIES OF MACHINED SPECIMENS FROM CAST AND FORGED RAILROAD WHEELS
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2012-01-01)
The worldwide tendency of railways is the high load per wagon in cargo transport and high speed in the passenger sector. In both situation the wheel is strongly required, especially in respect of fatigue, which have being ...
Effect of residual stresses and inclusion size on fatigue resistance of parabollic steel springs
(Carl Hanser Verlag, 2014-04-08)
The effect of inclusion size and residual stresses of spring steel grade 51CrV4 on fatigue lifetime in high cycle was investigated by experimental results obtained by fatigue testing. Since spring with obvious surface ...
