Fatigue crack growth rates under variable amplitude load spectra containing tensile underloads [PDF]
, 2003 An extensive research program was performed to investigate the load interaction effect of the combined action of small amplitude high R ratio cycles and large amplitude low R ratio underloads on the crack growth of large cracks.

Experimental measurement and model validation of COD in pipe under bending with off-centered circumferential crack [PDF]
Fracture and Structural Integrity, 2014 The leak area of circumferential through-thickness crack in pipe under bending depends on the position of the crack with respect to the bending plane. In leak-before-break (LBB) analysis, the assumption that the crack is symmetrically placed with respect

Characterization on crack propagation of nuclear graphite under three-point bending
Nuclear Materials and Energy, 2019 The fracture properties of graphite produced in China, named as CLG, were studied by performing three-point bending tests on center-notched beams. The load-deflection (P-δ) curves and load-crack mouth opening displacement (P-CMOD) curves of the beams in ...

A numerical study of crack shielding and deflection under extensive plasticity [PDF]
, 2009 Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

The effect of a capillary bridge on the crack opening of a penny crack [PDF]
, 2016 Young's relation is based on the equilibrium of horizontal components of surface tensions for a liquid droplet on a "rigid'' substrate without addressing the substrate deformation induced by the net vertical component of surface tensions.

The effect of low-cycle fatigue on evolution of fracture mechanics parameters in residual stress field caused by cold hole expansion [PDF]
Fracture and Structural Integrity, 2019 Localized displacement measurements based on electronic speckle-pattern interferometry are used to obtain crack mouth opening displacement (CMOD), stress intensity factor (SIF) and T-stress values during crack growth around cold-expanded holes.
