Fatigue behaviour study on repaired aramid fiber/epoxy composites
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 ...
Fatigue in Brazilian cancer patients, caregivers, and nursing students: a psychometric validation study of the Piper Fatigue Scale-Revised
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 crack growth assessments in welded components including crack closure effects: Experiments and 3-D numerical modeling
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 ...
Evaluation of the fretting fatigue behaviour of commercially pure titanium
(Professional Engineering Publishing Ltd, 2014)
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 ...
The influence of muscle fatigue on walking: The role of aging and Parkinson's disease
Muscle fatigue causes motor adjustments in functional activities, including locomotion. Fatigue development is mediated by a range of individual factors such as the presence of pathologies, age, physical activity level, ...
Is fatigue after work a barrier for leisure-time physical activity? Cross-sectional study among 10,000 adults from the general working population
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 ...
