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.

Experimental evaluation of plasticity-induced crack shielding from crack tip displacements fields [PDF]
Fracture and Structural Integrity, 2015 In this work it is proposed a methodology for the evaluation of plasticity-induced crack shielding from the analysis of the crack tip displacements fields measured by digital image correlation.

Stress Intensity Factor calculation from displacement fields [PDF]
Fracture and Structural Integrity, 2017 In the last two decades, visual image techniques such as Digital Image Correlation (DIC) enabled to experimentally determine the crack tip displacement and strain fields at small scales. The displacements are tracked during loading, and parameters as the

Mixed-mode crack tip fields in a polycrystalline aluminum alloy [PDF]
MATEC Web of Conferences, 2019 Carefully performed experiments with long cracks in the near-threshold regime have shown that the crack tip field of these cracks significantly deviate from the expected mode-I butterfly-shaped ones and resemble strongly to mixed-mode crack tip fields. A

Characterisation of crack tip fields—CCTF5 [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2020 Single parameter characterisation of the crack/notch tip field using fracture mechanics parameters like K, J, or CTOD has been extremely powerful in advancing predictive technologies for critical or subcritical crack growth. It has also become clear over

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
