Micromechanisms of short fatigue crack growth in an Al-Si piston alloy [PDF]

open access: yes, 2014
The short fatigue crack growth behaviour of a model cast aluminium piston alloy has been investigated. This has been achieved using a combination of fatigue crack replication methods at various intervals during fatigue testing and post-mortem analysis of

Analysis on Fatigue Crack Initiation and Fatigue Crack Propagation in a Gear

open access: yesSMART MOVES JOURNAL IJOSCIENCE, 2017
An effective gear design balances strength, durability, reliability, size, weight and cost. Because of the advantage of gear, gearbox was used widely. But its fault also brought many losses of the production and society. It was necessary to research and analysis on the dynamical behavior of the gear system.

Stress-state dependent cohesive model for fatigue crack growth [PDF]

open access: yesFracture and Structural Integrity, 2016
In the cohesive framework, a stress-state dependent cohesive model, combined with an irreversible damage parameter has been used in simulation of fatigue crack growth initiation and continued growth.

Introduction of a fretting-fatigue mapping concept: Development of a dual crack nucleation - crack propagation approach to formalize fretting-fatigue damage [PDF]

open access: yes, 2009
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components.

A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]

open access: yes, 2010
It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.

Effect of high temperature on crack initiation of super austenitic stainless steel 654SMO in very high cycle fatigue

open access: yesMaterials & Design, 2020
Working service of structural materials at elevated temperatures generally leads to a significant decrease in their fatigue performance, thereby threatening the safety and reliability of engineering structures.

A predictive fatigue life model for anodized 7050 aluminium alloy [PDF]

open access: yes, 2013
The objective of this study is to predict fatigue life of anodized 7050 aluminum alloy specimens. In the case of anodized 7050-T7451 alloy, fractographic observations of fatigue tested specimens showed that pickling pits were the predominant sites for ...

Fatigue Crack Initiation and Propagation [PDF]

open access: yes, 2019
The resistance of metal alloys to fatigue can be classified into four major regimes: low-cycle fatigue (or short life), limited resistance (between 10^5 and 10^6 cycles), high-cycle fatigue (between 10^6 and 10^7 cycles) and gigacycle (more than10^7 cycles).

Forecast of the fatigue crack initiation site of commercially pure Titanium miniature specimens with local surface topography data [PDF]

open access: yesMATEC Web of Conferences, 2020
Surfaces of technical components rarely appear in perfectly smooth condition. During fatigue loading, stress concentrations at surface asperities cause localized plastic deformation that can lead to crack initiation.
