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 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 ...
Estimation of the plain high-cycle fatigue propagation resistance in steels
(Universidade Federal de São Carlos, 2002-12)
In this work a method to estimate the high cyclic fatigue propagation life of steel specimens under constant loading is presented. This method is based in experimental evidence that the fatigue limit represents the threshold ...
Numerical life estimation after fatigue failure of a complex component
(Wiley Blackwell Publishing, Inc, 2005-06)
Failure of a large ethylene‐reciprocating compressor was found to be due to fatigue growth of cracks in the crosshead of one of the cylinders, initiated at material defects near stress raisers. Total fatigue crack growth ...
Factors influencing transit fatigue of seamless pipes
(Wiley Blackwell Publishing, Inc, 2005-05)
Full‐scale fatigue tests simulating real pipe stock conditions in ships were carried out in order to reproduce failures of seamless pipes due to fatigue crack growth during shipping. Simple mechanical analyses were then ...
Fatigue assessment of a double submerged arc welded gas pipeline
(Elsevier, 2007-06)
An uncommon blow out in a 24″ diameter, 7 mm thick API 5L X52 gas pipeline was due to fracture at the longitudinal double submerged arc weld (DSAW). Fatigue cracks were found to have initiated from a large embedded weld ...
Fatigue life of GMAW and PAW welding joints of boron microalloyed steels
(Elsevier, 2015-09)
Recently boron microalloyed steels have become an alternative in weight saving in structural elements in automotive industry,especially for parts like pillars and columns and reinforcements. These materials are used as ...
Modeling of wind-induced fatigue of cold-formed steel sheet panels
(Techno-Press, 2014-01)
Wind-induced failure around screwed connections has been documented in roof and wall cladding systems made with steel sheet cold-formed panels during high wind events. Previous research has found that low cycle fatigue ...
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. ...
Experimental analysis on the combined effects of corrosion and fatigue in reinforced concrete beams
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2019)
