High cycle thermal fatigue of austenitic stainless steel

open access: yesMATEC Web of Conferences, 2018
A new experimental setup called FLASH (THErmal Fatigue by LASer or Helium pulses) has been developed to perform thermal fatigue tests on materials used in structures of Sodium-cooled Fast Reactors (SFRs).

Properties of the Fine Granular Area and Postulated Models for Its Formation during Very High Cycle Fatigue—A Review

open access: yesApplied Sciences, 2020
Understanding the mechanisms leading to very high cycle fatigue is necessary to make predictions about the behavior under various conditions and to ensure safe design over the whole lifetime of high-performance components.

Very-high-cycle fatigue behavior of Ti-6Al-4V manufactured by selective laser melting: Effect of build orientation

open access: yes, 2020
The effect of building orientation on the very-high-cycle fatigue (VHCF) response of Ti-6Al-4V specimens produced through selective laser melting (SLM) process with three different building orientations (0°, 45° and 90°) has been experimentally assessed.

Influence of non-metallic inclusions on the high cycle fatigue strength of steels

open access: yesInternational Journal of Fatigue, 2022
In the present paper, a criterion for fatigue assessment of high strength steels is proposed, where the influence of non-metallic inclusions on fatigue life is taken into account. To such an aim, the Carpinteri et al.

Investigation of very high cycle fatigue by thermographyc method [PDF]

open access: yesFracture and Structural Integrity, 2014
Nowadays, many components and structures are subjected to fatigue loading with a number of cycles higher than 107. In this scientific work, the behaviour of two kinds of tool steel was investigated in very high cycle fatigue regime.

Crack initiation mechanisms and life prediction of GH4169 superalloy in the high cycle and very high cycle fatigue regime

open access: yesJournal of Materials Research and Technology, 2023
In this study, the high cycle and very high cycle fatigue behavior of the GH4169 superalloy was investigated. The results of the fatigue tests demonstrated that failures in the high cycle fatigue regime were initiated from the material surface, whereas ...

Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings [PDF]

open access: yes, 2013
Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior importance for the applicability of

A Modified Fatigue Damage Model for High-Cycle Fatigue Life Prediction

open access: yesAdvances in Materials Science and Engineering, 2016
Based on the assumption of quasibrittle failure under high-cycle fatigue for the metal material, the damage constitutive equation and the modified damage evolution equation are obtained with continuum damage mechanics.

High cycle fatigue behaviour of magnesium alloys

open access: yesProcedia Engineering, 2010
AbstractThe influence of crystallographic texture on fatigue failure mechanisms was studied by comparing the fatigue behaviour of two extruded magnesium alloys, AZ31 and ZN11. The microstructures and fracture surfaces of specimens were examined using scanning electron microscopy (SEM) to reveal the micromechanisms of fatigue crack initiation.

Types of rotor failure and characteristics of fragments [PDF]

open access: yes, 1977
Noncontained rotor failures in U.K. engines resulting from low cycle fatigue, low cycle fatigue with superimposed high cycle fatigue, and overheating and-or overspeeding were analyzed.
