Quality assessment of speckle patterns for digital image correlation
David Lecompte,Arwen Smits,Sven Bossuyt,Hugo Sol,Johnny Vantomme,D. Van Hemelrijck,Anne Habraken +6 more
TL;DR: A comparison is made between three different speckle patterns originated by the same referenceSpeckle pattern, and it is shown that the size of the speckles combined with thesize of the used pixel subset clearly influences the accuracy of the measured displacements.

Stress intensity factor measurements from digital image correlation: post-processing and integrated approaches
Stéphane Roux,François Hild +1 more
TL;DR: In this article, the crack geometry and the crack opening displacement are evaluated from image correlation by following two different measurement and identification routes, and the stress intensity factor is estimated with a 7% uncertainty in a complex loading set-up.

Digital Imaging Techniques In Experimental Stress Analysis
W. H. Peters,W. F. Ranson +1 more
TL;DR: In this paper, the surface displacement components in laser speckle metrology were measured using a digital image scanner interfaced to a computer. Butt et al. used a boundary integral equation method to calculate surface traction in the contour.

Digital image correlation using Newton-Raphson method of partial differential correction
TL;DR: In this paper, the authors developed and limited experimental verification of a method which can determine displacements and gradients using the Newton-Raphson method of partial corrections, which was shown to be accurate in determining displacement and certain gradients, while using significantly less CPU time than the current coarse-fine search method.
