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 ...
Electromyographic fatigue threshold of the biceps brachii muscle during dynamic contraction
(2005-04-01)
The purpose of this study was to identify the Electromyographic Fatigue Threshold (EMG FT) of the biceps brachii muscle bilaterally during the elbow flexion in tests performed in different times: 30 second test, 1 minute ...

Fatigue damage accumulation in aluminum 7050-T7451 alloy subjected to block programs loading under step-down sequence
(Elsevier B.V., 2010-01-01)
In this paper the fatigue damage accumulation under block program loading is investigated. Alternative flexion bending fatigue tests with a single change in stress amplitude are performed at room temperature for step-down ...
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 evaluation of shot peening, residual stress and stress relaxation on the fatigue life of AISI 4340 steel
(Elsevier B.V., 2002-08-01)
Shot peening is a method widely used to improve the fatigue strength of materials. through the creation of a compressive residual stress field (CRSF) in their surface layers. In the present research the gain in fatigue ...

Low-cycle fatigue behaviour of reinforcing bars including the effect of inelastic buckling
(Elsevier Ltd, 2018)
Low-cycle fatigue life of Grade 300E and 500E reinforcing bars including the effect of buckling is evaluated. Low-cycle fatigue tests are carried out on un-machined specimens subjected to constant axial strain loading with ...
Investigation of the damage and fracture of Ti-6Al-4V titanium alloy under dwell-fatigue loadings
(2021-01-01)
Ti-6Al-4V alloy turbine components for aeronautical applications operate at a steady state after reaching the maximum stress during each duty cycle. The load holds combined with the fatigue process causes a phenomenon ...
