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
(2017-02-07)
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, ...
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 ...
Analyses of fatigue data in 4340 high strength steel after cadmium electroplating
(Technical Research Centre Finland, 1998-01-01)
Bending fatigue tests were carried out to clarify the effects of heat treatment parameters: temperature and time after cadmium electroplating on a high strength steel, to avoid hydrogen embrittlement. Temperatures heat of ...
