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 ...

Motor strategy during postural control is not muscle fatigue joint-dependent, but muscle fatigue increases postural asymmetry
(2021-02-01)
The aim of this study was to investigate the effects of ankle and hip muscle fatigue on motor adjustments (experiment 1) and symmetry (experiment 2) of postural control during a quiet standing task. Twenty-three young ...
Fatigue in Brazilian cancer patients, caregivers, and nursing students: a psychometric validation study of the Piper Fatigue Scale-Revised
(SPRINGER, 2009)
The objective of this study was to validate the Piper Fatigue Scale-Revised (PFS-R) for use in Brazilian culture. Translation of the PFS-R into Portuguese and validity and reliability tests were performed. Convenience ...
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 ...
Fatigue behavior of PVD coated Ti-6Al-4V alloy
(Elsevier B.V., 2011-06-01)
The aim of the present work is to identify an environmentally clean coating process that will present lower influence in the Ti-6Al-4V fatigue strength. Axial fatigue tests of Ti-6Al-4V alloy TiN, CrN and WC:H (tungsten ...

Fatigue crack growth assessments in welded components including crack closure effects: Experiments and 3-D numerical modeling
(Kidlington, 2014-02-04)
This work provides a numerical and experimental investigation of fatigue crack growth behavior in steel
weldments including crack closure effects and their coupled interaction with weld strength mismatch. A
central ...
Fatigue notch sensitivity of steel blunt-notched specimens
(Wiley Blackwell Publishing, Inc, 2002-07)
The notch sensitivity of three steels with similar plain fatigue limits was analysed and modelled. The analysis was made by using a model previously derived which estimated the fatigue limit of blunt notched components by ...
Residual stress influence on fatigue lifetimes of electroplated AISI 4340 high strength steel
(Blackwell Publishing, 2007-11-01)
Residual stresses play an important role in the fatigue lives of structural engineering components. In the case of near surface tensile residual stresses, the initiation and propagation phases of fatigue process are ...
