As a carrier of deformation information, the speckle pattern, or more exactly the random
intensity distributions, which could be naturally occurred or artificially fabricated onto test …

Abstract 3D imaging has become popular for analyzing material microstructures. When time
lapse series of 3D pictures are acquired during a single experiment, it is possible to …

OpenCorr is an open source C++ library made for research and development of digital
image correlation (DIC) technology. It provides full-function modules of 2D and stereo DIC …

Over the past years, we have been develo** new algorithms and approaches for robust,
efficient and accurate internal displacement and strain field measurements using digital …

The measurement accuracy using the digital image correlation (DIC) method in local
deformations such as the Portevin–Le Chatelier bands, the deformations near the gap, and …

In subset-based digital image correlation (DIC), a proper shape function must be chosen to
approximate the underlying displacement field of the target subsets to ensure an accurate …

Digital volume correlation (DVC) has evolved into a powerful tool for quantifying full-field
internal deformation. In existing subvolume-based local DVC, subvolume size and shape …

The random errors of subset-based digital image correlation due to the use of matched or
overmatched shape functions are investigated. Governing formulations that can …

Characterizing material 3D deformation and damage is a key challenge in mechanical
research. Digital volume correlation (DVC), as a tool for quantifying the internal mechanical …
