An evaluation of shot peening, residual stress and stress relaxation on the fatigue life of AISI 4340 steel
(Elsevier B.V., 2002-08-01)
Shot peening is a method widely used to improve the fatigue strength of materials. through the creation of a compressive residual stress field (CRSF) in their surface layers. In the present research the gain in fatigue ...
FATIGUE PROPERTIES OF MACHINED SPECIMENS FROM CAST AND FORGED RAILROAD WHEELS
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2012-01-01)
The worldwide tendency of railways is the high load per wagon in cargo transport and high speed in the passenger sector. In both situation the wheel is strongly required, especially in respect of fatigue, which have being ...
Low-cycle fatigue behaviour of reinforcing bars including the effect of inelastic buckling
(Elsevier Ltd, 2018)
Low-cycle fatigue life of Grade 300E and 500E reinforcing bars including the effect of buckling is evaluated. Low-cycle fatigue tests are carried out on un-machined specimens subjected to constant axial strain loading with ...
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 ...
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 ...
Evaluation of the fretting fatigue behaviour of commercially pure titanium
(Professional Engineering Publishing Ltd, 2007-07-01)
Fretting fatigue occurs when the contact surfaces of two components undergo small oscillatory movement while they are subjected to a clamping force. A cyclic external load gives rise to the early initiation of fatigue ...

Effects of physical activity levels on fatigue perception in patients with Parkinson's disease and neurologically healthy individuals
(2014)
Background: Recent researches involving fatigue and Parkinson’s disease (PD) sought to verify its incidence and the impacts of fatigue on quality life of patients with PD. Despite the importance of regular physical activity ...
Fatigue crack propagation of aeronautic AA7050-T7451 and AA2050-T84 aluminum alloys in air and saline environments
(2022-01-01)
AA7050-T7451 aluminum alloy is one of the most used material in aeronautical applications due to its high strength/density ratio and good fatigue resistance. More recently the AA2050-T84 alloy was introduced due to its ...
