Effect of low temperature on fatigue and crack propagation behavior of aeronautic aluminium alloy
Journal of Aeronautical Materials, 2021 Fatigue and crack growth tests were performed on two categories of the common aeronautic aluminum- alloys 2524-T3 and 7050-T7451 at ambient temperature of 25 ℃ and cryogenic temperature of –70 ℃, in order to investigate the fatigue and crack propagation ...

3D modelling of fatigue crack growth and life predictions using ANSYS
Ain Shams Engineering Journal, 2022 This study uses ANSYS mechanical APDL 19.2 to predict crack propagation trajectories and fatigue crack growth at constant amplitude loading. Mixed-mode fatigue life assessment is implemented by the Paris law model for different configuration of modified ...

The influence of crack tip shielding on fatigue crack propagation [PDF]
Fracture and Structural Integrity, 2017 The fatigue crack propagation is one of the major problems and of the real concern in the evaluation of the structural integrity of components. This is due to the fact that once a fatigue crack has been detected it is also known its effect on the ...

FATIGUE CRACK NUCLEATION IN METALS [PDF]
Proceedings of the National Academy of Sciences, 1969 One of the unanswered questions in the study of fatigue is how cracks nucleate at stresses far below the static fracture strength. Previous theories show possible qualitative mechanisms that may operate in a crystal at room and low temperatures but none provides a quantitiative theory of this phenomenon. We show here a quantitative mechanism of fatigue

Fatigue crack surface area and crack front length: new ways to look at fatigue crack growth [PDF]
MATEC Web of Conferences, 2018 This paper discusses the appropriateness of crack length as a reference dimension for fatigue damage. Current discussion on short crack versus long crack data is still divided between various approaches to model small crack growth. A proper physical explanation of the probable cause of the apparent differences between short crack and long crack data is

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