Effect of crack propagation on crack tip fields [PDF]
Fracture and Structural Integrity, 2013 Crack closure influences fatigue crack growth rate and must be included in the design of components. Plasticity induced crack closure is intimately linked with the crack tip plastic deformation, which becomes residual as the crack propagates.

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

Elastic-plastic analysis of crack on bimaterial interface [PDF]
Theoretical and Applied Mechanics, 2005 In this paper are presented solutions for the stress and displacement fields for a crack that lies along the interface of an elastic and elastic - plastic material and for a crack between two different elastic - plastic materials.

Вестник Самарского университета: Естественнонаучная серия, 2023 The research is devoted to the study of the stress field at the crack tip in an anisotropic material with three mutually orthogonal axes of symmetry of the fourth order (with cubic symmetry). A plane case is considered when one of the axes of symmetry is

Application of J2 Integral Method in Calculating Complicated Stress Intensity Factors on Three-dimensional Components [PDF]
E3S Web of Conferences, 2021 In this paper, a technique to determine complicated stress intensity factors on three-dimensional components, which based on the conservation law and the elementary mechanics is proposed, it only needs the geometric relationship between multiple singular

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 ...

Medžiagotyra, 2022 This paper deals with the effect of initial crack tip shape, plastic compressibility, and strain softening on near-tip stress-strain fields for a mode I crack subjected to fatigue loading under plane strain and small scale yielding. A finite strain-based

Modelling probabilistic fatigue crack propagation rates for a mild structural steel [PDF]
Fracture and Structural Integrity, 2015 A class of fatigue crack growth models based on elastic–plastic stress–strain histories at the crack tip region and local strain-life damage models have been proposed in literature.
