Measurement of Crack Tip Opening Displacement and Strain Fields Using Global Digital Image Correlation (DIC)

58th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: The assessment of fracture properties such as crack tip opening displacement (CTOD), plastic zone size, and crack development is essential for understanding the behavior of cracks and fractures in geological materials.

Using the Multi-Parameter Fracture Mechanics for more Accurate Description of Stress/Displacement Crack Tip Fields

Key Engineering Materials, 2013
Most of fracture analyses often require an accurate knowledge of the stress/displacement field over the investigated body. However, this can be sometimes problematic when only one (singular) term of the Williams expansion is considered. Therefore, also other terms should be taken into account.

Fatigue Crack-Tip Mechanics in 7075-T6 Aluminum Alloy from High-Sensitivity Displacement Field Measurements

1988
The fatigue crack-tip deformation in the 7075-T6 aluminum alloy has been studied by moiré interferometry, which is a coherent optics technique for full-field in-plane displacement measurements in the submicrometre range. For constant-amplitude-loading conditions the local strain distributions and the crack-tip plasticity have been correlated with ...
