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 ...
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 ...
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 ...
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 ...
Effect of triceps surae and quadriceps muscle fatigue on the mechanics of landing in stepping down in ongoing gait
(Taylor & Francis Ltd, 2014-06-01)
The aim of this study was to evaluate the effects of muscle fatigue of triceps surae and quadriceps muscles in stepping down in ongoing gait. We expected that the subjects would compensate for muscle fatigue to prevent ...
Recovery of gait after quadriceps muscle fatigue
(Elsevier B. V., 2015-10-25)
The aim of this study was to investigate the effect of recovery time after quadriceps muscle fatigue on gait in young adults. Forty young adults (20-40 years old) performed three 8-m gait trials at preferred velocity before ...
Interactions of age and leg muscle fatigue on unobstructed walking and obstacle crossing
(Elsevier B.V., 2014-03-01)
Older adults commonly report muscle fatigue, which may be associated with reduced walking ability. Elderly may have insufficient awareness of the balance threat caused by muscle fatigue. The aim of this study was to analyze ...
Is fatigue after work a barrier for leisure-time physical activity? Cross-sectional study among 10,000 adults from the general working population
(2018-04-01)
Aim: In spite of the many health-related benefits of regular physical activity, fatiguing work may be a barrier to performing leisure-time physical activity. This study investigates the association between work-related ...
Fatigue fracture behavior of Ti-6Al-4V PVD coated
(Elsevier B.V., 2010-01-01)
Fatigue, corrosion and wear resistance are important parameters in aircraft components development as landing gear. High strength/weight ratio and effective corrosion resistance make of titanium alloys an alternative choice ...
