Effects of electroplated zinc-nickel alloy coatings on the fatigue strength of AISI 4340 high strength steel
(2005-12-01)
It is well known that fatigue behaviour is an important parameter to be considered in mechanical components subjected to constant and variable amplitude loadings. In combination with corrosion phenomenon, fatigue effects ...
Microstructural effects on fatigue crack growth behavior of a microalloyed steel
(2010-04-01)
Thermal transformations on microalloyed steels can produce multiphase microstructures with different amounts of ferrite, martensite, bainite and retained austenite. These different phases, with distinct morphologies, are ...
INFLUENCE OF HVOF COATING ON THE FATIGUE STRENGTH OF 15-5 PH STAINLESS STEEL
(Trans Tech Publications Ltd, 2014-01-01)
Structural component failures due to cyclic loading are associated to surface damage of materials and its interaction with environment. Fatigue failure occurs with stresses below the yield strength of each material and is ...
Fatigue Strength of X45CrSi93 stainless steel applied as internal combustion engine valves
(Elsevier B.V., 2011-01-01)
Stainless steels are used to intake and exhaust valves production applied as internal combustion engines. In general valves are requested to support cyclic stresses applied due to opening and closing processes during the ...
EVALUATION OF HVOF SPRAYED WC-13Co-4Cr AND HARD CHROMIUM ELECTROPLATED ON STAINLESS STEEL 15-5PH FATIGUE STRENGTH
(Inegi-feup, 2017-01-01)
Fatigue failure is the result of a crack initiation and propagation as a consequence of cyclic loading. In the aeronautical industry, for components like landing gear, fatigue strength is an important parameter to be ...
Analysis of fatigue failure in the rolling bearings
(2013-01-01)
The development of the technology of rolling bearings, such as cylindrical or thrust bearings has as one of its objectives constitute a set of mechanical components that combine mechanical strength and stiffness, designed ...
Fracture analysis in 5HS carbon composites subjected to pure modes I and II fatigue induced delamination
(2014-01-01)
Interlaminar fracture process in woven composite laminate in general takes place in a nonlinear front propagation when analyzing a 2-D propagation for mode I opening. The nonlinearity is justified by the arresting crack ...
Study of fatigue crack growth in al-mg-si alloys using a predictive model under positive and negative load ratios
(2014-01-01)
The study of fatigue crack growth (FCG) is aimed at residual life estimations in order to apply the damage tolerant criterion. Usual approaches are based on semi-empirical models that consider the stress intensity factor ...
Numerical model for the stress field ahead of a crack in elastoplastic regime
(2019-01-01)
Damage-tolerant designs admit the pre-existence of defects and small cracks, which lead to stress redistribution in structural components. The accurate knowledge of the stress field in parts under these conditions is ...
Automotive wheels - An approach for structural analysis and fatigue life prediction
(2001-01-01)
Wheels are components working under cyclic loading and different load spectrum considering the load amplitude and frequency. Wheels can be considered an item of a vehicle security but restrictions about the weight are ...
