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 ...
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 ...
Estudo da fadiga de contato em engrenagens cilíndricas de dentes retos
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Mecânica e de Materiais, 2009-03-27)
Due to the resistance of automotive manufactures on apply ADI gear studies have been made to verify the performance of this material. Inside this context this work has a main objective the construction of contact fatigue ...
Comparison of cyclic fatigue and torsional resistance in reciprocating single-file systems and continuous rotary instrumentation systems
(Nihon Univ, School Dentistry, 2014-12-01)
As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file ...
Fatigue in multiple sclerosis is associated to multimodal interoceptive abnormalities
(Sage Publications Ltd, 2019-11)
Background: Fatigue ranks among the most common and disabling symptoms in multiple sclerosis (MS). Recent theoretical works have surmised that this trait might be related to alterations across interoceptive mechanisms. ...
Scrutinizing interlaminar fatigue loading cycle in composites using acoustic emission technique: Stress ratio influence on damage formation
(2020-11-01)
Current models for delamination propagation prediction in fiber-reinforced polymer (FRP) composites exhibit limitations to explain the physics underlying the mechanisms of damage formation in fatigue. In order to contribute ...
Driver alert state and fatigue detection by salient points analysis
(IEEE, 2009)
Assessing a driver's state of awarness and fatigue is especially important to reduce the number of traffic accidents often involving bus and truck drivers, who must work during several hours under monotonous road conditions. ...
Influence of shot peening on the fatigue strength of Custom 465 stainless steel for aeronautic application
(Trans Tech Publications Ltd, 2014)
Fatigue of NiTi shape memory wires
(Elsevier, 2016)
In the present work, an innovative methodology for characterizing structural fatigue of NiTi superelastic wires is proposed. It consists in, firstly, performing low speed nearly isothermal pseudoelastic cycles in a limited ...
