The post-yield fracture of a ductile polymer film: Notch quality, essential work of fracture, crack tip opening displacement, and J-integral [PDF]
Engineering Fracture Mechanics, 2017 Double edge notched tension (DENT) specimens of a polyethylene terephthalate (PET) film were tested in an universal testing machine, measuring the displacements and the ligament lengths with a digital image correlation (DIC) system.

Study of Crack Closure Effect of Hull Plate under Low Cycle Fatigue
Journal of Marine Science and Engineering, 2022 The crack closure phenomenon significantly influences low cycle fatigue (LCF) crack growth. The crack closure theory deems that a crack can grow only when the applied load is greater than the fatigue crack opening and closing loads.

Effect of numerical parameters on plastic CTOD [PDF]
Fracture and Structural Integrity, 2017 Fatigue crack growth (FCG) is associated with irreversible and non-linear processes happening at the crack tip. This explains different problems observed in the use of da/dN-?K curves, namely the inability to explain stress ratio and load history effects.

Modelling of Crack Growth Using a New Fracture Criteria Based Peridynamics [PDF]
Journal of Applied and Computational Mechanics, 2019 Peridynamics (PD) is a nonlocal continuum theory based on integro-differential equations without spatial derivatives. The elongation fracture criterion is implicitly incorporated in the PD theory, and fracture is a natural outcome of the simulation.

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
