Materials Today, 2010 Digital image correlation (DIC) is a classic pattern recognition technique that is widely used for experimental measurements, mainly for: (1) surface displacement analysis in solid mechanics, and (2) particle image velocimetry (PIV) in fluid mechanics. DIC is based on using a correlation function to locate the best matching position of two images thus ...

Mechanics-aided digital image correlation [PDF]
The Journal of Strain Analysis for Engineering Design, 2013 By construction, digital image correlation is an ill-posed problem. To circumvent this difficulty, regularization is often performed implicitly through the kinematic basis chosen to express the sought displacement fields. Conversely, a priori information on the mechanical behavior of the studied material is often available.

On the Digital Image Correlation Technique
Materials Today: Proceedings, 2022 Abstract This study has been focused in the introduction of the theoretical and practical foundations of the Digital Image Correlation DIC technique to undergraduate students at EPN through the implementation of a Laboratory DIC practice. In the experimental test, an elastomer with different hole shapes is used as a test specimen, which should have a
