Fatigue behavior of bainitic and martensitic super clean Cr–Si high strength steels.
(Oxford, 2014-04)
This study compares the fatigue behavior of quenched/tempered and austempered super clean Cr–Si high strength steels (HSS). The microstructure of the quenched and tempered steel consisted of tempered martensite and that ...
The potential of spinodal ferrite decomposition for increasing the very high cycle fatigue strength of duplex stainless steel
(Elsevier, 2016-12)
Duplex stainless steels (DSS) have become candidate materials for structural applications, where conventional austenitic stainless steels fail due to very high cycle fatigue (VHCF) in combination with corrosive attack. It ...
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 ...
Two competing crack growth mechanisms in very high pressures tubes
(Elsevier, 2010-09-25)
This work addresses the influence of autofrettage in the occurrence of repeated leaks of thick wall straight and curved 4333M4 steel tubes from a high pressure petrochemical reactor, comprised by straight and curved tubes ...
Stress-dependence of young´s modulus of Ti 6242S at high temperatures during uniaxial LCF tests
(Universidad de Los Andes, 2009)
Effect of the shot peening process on the fatigue strength of SAE 5160 steel
(2019-06-01)
The fatigue behaviour of SAE 5160 steel was evaluated before and after applying a shot peening process by using different Almen intensities and surface coverings (uncovered, partial coverage and total coverage). In the ...
The effects of priming exercise on the (V)over dotO(2) slow component and the time-course of muscle fatigue during very-heavy-intensity exercise in humans
(Canadian Science Publishing, Nrc Research Press, 2018-09-01)
We hypothesized that prior exercise would attenuate the muscle fatigue accompanied by oxygen uptake slow-component ((V)over dotO(2SC)) behavior during a subsequent very-heavy (VH)-intensity cycling exercise. Thirteen healthy ...
Estimativa de vida em fadiga de estruturas submetidas a excitações randômicas e análise comparativa com resultados de ensaios de durabilidade
(Universidade Estadual Paulista (Unesp), 2022-08-01)
Considerando as dificuldades da etapa de dimensionamento por fadiga de estruturas submetidas à carregamentos dinâmicos randômicos, a escolha da metodologia para estimativa de vida em fadiga destas estruturas é muito relevante ...
Effect of the shot peening process on the fatigue strength of SAE 5160 steel
(Sage, 2018)
The fatigue behaviour of SAE 5160 steel was evaluated before and after applying a shot peening process by using different Almen intensities and surface coverings (uncovered, partial coverage and total coverage). In the ...
