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.

Determining mode I cohesive law of Pinus pinaster by coupling double cantilever beam test with digital image correlation [PDF]
Fracture and Structural Integrity, 2015 The direct identification of the cohesive law in pure mode I of Pinus pinaster is addressed. The approach couples the double cantilever beam (DCB) test with digital image correlation (DIC).

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.
