Stress intensity factor of wood from crack-tip displacement fields obtained from digital image processing [PDF]
Silva Fennica, 2004 Stress intensity factor of radiata pine (Pinus radiata) in Tangential-Longitudinal opening mode was determined from crack-tip displacement fields obtained from digital image correlation in conjunction with orthotropic fracture theory. For lower loads,

Variable mode-mixity during fatigue cycles – crack tip parameters determined from displacement fields measured by digital image correlation [PDF]
Fracture and Structural Integrity, 2017 This paper focusses on discussing equivalent stress intensity factors and kink angles after a change of mode-mixity from one cycle to the next and when the mode-mixity changes continuously during the fatigue cycles.

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

Quantifying crack tip displacement fields with DIC [PDF]
Engineering Fracture Mechanics, 2010 Crack paths under both fatigue and fracture conditions are governed by the crack tip displacement field and the material deformation characteristics, including those influenced by metallurgical anisotropy. Experimental techniques such as thermoelasticity and photoelasticity have been successfully used to characterise the elastic stress fields around ...
