Crack tip strain evolution and crack closure during overload of a growing fatigue crack [PDF]
Fracture and Structural Integrity, 2017 It is generally accepted that fatigue crack growth is retarded after an overload, which has been explained either by plasticity-induced crack closure or near-tip residual stress.

A numerical study of non-linear crack tip parameters [PDF]
Fracture and Structural Integrity, 2015 Crack closure concept has been widely used to explain different issues of fatigue crack propagation. However, different authors have questioned the relevance of crack closure and have proposed alternative concepts.

Near tip strain evolution of a growing fatigue crack [PDF]
Fracture and Structural Integrity, 2015 Near tip full-field strains in a growing fatigue crack have been studied in situ using the Digital Image Correlation (DIC) technique in a compact tension specimen of stainless steel 316L under tension-tension cyclic loading.

Study of overload effects in bainitic steel by synchrotron X-ray diffraction [PDF]
Fracture and Structural Integrity, 2013 This work presents an in-situ characterisation of crack-tip strain fields following an overload by means of synchrotron X-ray diffraction. The study is made on very fine grained bainitic steel, thus allowing a very high resolution so that small changes ...

The failure criterion based on hydrogen distribution ahead of the fatigue crack tip [PDF]
Fracture and Structural Integrity, 2013 The hydrogen effect on the fracture toughness and fatigue crack growth behaviour in the martensitic high strength steel is investigated. The secondary ion mass spectrometry method has been employed to analyse the distribution of hydrogen concentration in

2D mapping of plane stress crack-tip fields following an overload [PDF]
Fracture and Structural Integrity, 2015 The evolution of crack-tip strain fields in a thin (plane stress) compact tension sample following an overload (OL) event has been studied using two different experimental techniques.

Strain-gradient effect on the crack tip dislocations density
Fracture and Structural Integrity, 2020 In this study, the influence of a material’s plastic properties on the crack tip fields and dislocation density behavior is analytically and numerically analyzed using the conventional mechanism-based strain-gradient plasticity (CMSGP) theory established

On stress singularity at crack tip in elasticity
Results in Physics, 2019 In order to gain a better understanding of the stress singularity at the crack tip in elasticity, the relevant solutions are investigated. Based on the rigorous solution of a plate containing a crack and its corresponding asymptotic expression, the ...

Crack mechanism and experimental verification on straightening of AZ31B magnesium alloy plate
Scientific Reports, 2023 When plates with edge cracks in the rolling process is straightened by cyclic tensile and compressive stress, the tip of edge crack always accompanied by stress concentration, which leads to crack propagation.
