The effect of shot peening on notched low cycle fatigue [PDF]
, 2011 The improvement in low cycle fatigue life created by shot peening ferritic heat resistant steel was investigated in components of varying geometries based on those found in conventional power station steam turbine blades.

A probabilistic high cycle fatigue model applied to cast Al-Si alloys [PDF]
, 2013 In this work, the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys is investigated. It is observed that two different coexisting fatigue initiation mechanisms can occur in these materials depending on the presence of different ...

Effect of low cycle fatigue pre-damage on very high cycle fatigue
Theoretical and Applied Mechanics Letters, 2012 AbstractCarbon-manganese steel is often applied in components of pipes in nuclear plant. Ultrasonic fatigue tests following low cycle fatigue (LCF) cycles damaged are used to study the strength of very high cycle fatigure (VHCF). The comparison of test results of simple VHCF and cumulative fatigue (LCF plus VHCF) shows that LCF load influences the ...

Behaviour of nionikral-70 in low-cycle fatigue
, 2017 Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) = -1) has been analysed. LCF tests are performed on a series of smooth bar shaped specimens, 11 x 11 x 95 mm, parent metal (PM ...

COMBINED HIGH AND LOW CYCLE FATIGUE LIFE PREDICTION MODEL TAKING ACCOUNT OF COUPLED DAMAGE
Jixie qiangduMechanical parts such as gas turbine blades are often subjected to low cycle fatigue caused by low⁃frequency centrifugal force and high cycle fatigue caused by high⁃frequency vibration loads during the working process,and the damage caused by the ...

MODELIZATION OF LOW CYCLE FATIGUE DAMAGE IN FRAMES
, 2000 Damage models based on the Continuum Damage Mechanics (CDM) include explicitly the coupling between damage and mechanical behavior and, therefore, are consistent with the definition of damage as a phenomenon with mechanical consequences. However, this kind of models is characterized by their complexity.

Impact of hydrogen on the high cycle fatigue behaviour of Inconel 718 in asymmetric push–pull mode at room temperature [PDF]
, 2015 The influence of hydrogen on the high cycle fatigue (HCF) behaviour of Inconel 718 has been studied at room temperature in asymmetric push–pull mode using an ultrasonic HCF test rig. Fatigue tests have been carried out in gaseous hydrogen (GH2) and in Ar

Energy dissipation in low cycle fatigue of austempered ductile irons
, 2003 An energy-based characterisation of the low cycle fatigue properties of an austempered ductile iron is proposed by extending an analogous approach previously adopted in high cycle fatigue studies.

Low-cycle and dwell fatigue properties for a near alpha titanium alloy Ti–6Al–3Nb–2Zr–1Mo
Journal of Materials Research and TechnologyAs a new type of marine titanium alloy, Ti–6Al–3Nb–2Zr–1Mo (Ti6321) has gained attention for its comprehensive properties such as high toughness, strength, weldability, and corrosion resistance. However, there are only a few reports on fatigue properties
