Phase-field models for fatigue crack growth [PDF]

open access: yesTheoretical and Applied Fracture Mechanics, 2019
We introduce a class of models based on near crack tip degradation of materials that can account for fracture growth under cyclic loads below the Griffith threshold. We incorporate the gradual degradation due to a cyclic load through a flow equation that decreases spatially varying parameters controlling the fracture toughness in the vicinity of the ...

A Crack Propagation Method for Pipelines with Interacting Corrosion and Crack Defects

open access: yesSensors, 2022
Corrosion and crack defects often exist at the same time in pipelines. The interaction impact between these defects could potentially affect the growth of the fatigue crack.

A flexible HCF modeling framework leading to a probabilistic multiaxial Kitagawa-Takahashi diagram [PDF]

open access: yes, 2014
This article describes a flexible modeling framework which leads to the construction of a probabilistic, multiaxial Kitagawa-Takahashi diagram. This framework has been developed following experimental observations that clearly indicate that two ...

Reconstruction of fan blade dynamic loading prior to its fracture

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022
To maintain the functionality of fan blades, it is important to know the distribution of dynamic stresses in the blade, their amplitude and vibration frequency. Understanding of the dynamic loading pattern will allow us to determine under what conditions

Simulation of Quasi-Static Crack Propagation by Adaptive Finite Element Method

open access: yesMetals, 2021
The finite element method (FEM) is a widely used technique in research, including but not restricted to the growth of cracks in engineering applications.

Development of a fretting-fatigue mapping concept: The effect of material properties and surface treatments [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.

Fretting fatigue crack propagation rate under variable loading conditions [PDF]

open access: yesFracture and Structural Integrity, 2016
Fretting fatigue experiments aim to represent industrial problems and most of them endure variable loading. Being able to assess lifetime of assemblies, especially for low propagation rate conditions, is essential as experimental validation is often ...

Fatigue of Fillet-welded Joint Assessment by the FEA Simulation of Damage Accumulation [PDF]

open access: yesИнженерно-строительный журнал, 2011
Fatigue strength evaluation of non-continuous incomplete penetration fillet-welded joints transferring stress flow by the S-N criteria incorporating the «Hot-spot stress» or «Notch-stress» approaches is dubious since the characteristic stress at the ...
