Study of Crack Closure Effect of Hull Plate under Low Cycle Fatigue
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.

In-situ observation of micro-cracking in a SiC/BN/SiC ceramic matrix composite under tension
Crack spacing and crack opening displacement values are critical for CMC damage and oxidation modeling. A tensile stage used with light and scanning electron microscopy (SEM) was utilized to evaluate micro-cracking under load in SiC/BN/SiC ceramic matrix

Modelling of Crack Growth Using a New Fracture Criteria Based Peridynamics [PDF]
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.

Experimental measurement and model validation of COD in pipe under bending with off-centered circumferential crack [PDF]
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
