Digital Image Correlation for Cement-based Materials and Structural Concrete Testing

open access: yesCivil Engineering Dimension, 2020
This paper presents the application of a low-cost digital image correlation (DIC) system for automated crack mapping. The system employed makes use of a conventional digital camera, a remote image recording controller, and an open-source digital image ...

Extended three-dimensional digital image correlation (X3D-DIC) [PDF]

open access: yesComptes Rendus. Mécanique, 2008
A correlation algorithm is proposed to measure full three-dimensional displacement fields in a three-dimensional domain. The chosen kinematic basis for this measurement is based on continuous finite-element shape functions. It is furthermore proposed to account for the presence of strong discontinuities, similarly to extended finite element schemes ...

A space–time approach in digital image correlation: Movie-DIC [PDF]

open access: yesOptics and Lasers in Engineering, 2011
A new method is proposed to estimate arbitrary velocity fields from a time series of images acquired by a single camera. This approach, here focused on a single spatial plus a time dimension, is specialized to the decomposition of the velocity field over rectangular shaped (finite-element) bilinear shape functions.

Particle image velocimetry and digital image correlation for determining the elasticity modulus in wood

open access: yesScientia Agricola, 2021
: Several non-destructive testing techniques have been improved and tested in recent years. The non-destructive testing techniques using particle image velocimetry (PIV) and digital image correlation (DIC) differ from conventional testing techniques, as ...

High resolution digital image correlation using proper generalized decomposition: PGD‐DIC [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2012
SUMMARYA new method is proposed to measure the finite element (FE) displacement field from a deformed image in comparison with a reference one. In opposition to standard FE approaches, the unknown displacement is sought as a sum of products of separated dimension functions.

Fracture toughness testing using photogrammetry and digital image correlation

open access: yesMethodsX, 2018
Digital image correlation (DIC) is an optical technique commonly used for measuring displacement fields by tracking artificially applied random speckle patterns, which can sometimes be a problem for tracking small-scale displacements. DIC is particularly

A Review of Surface Deformation and Strain Measurement Using Two-Dimensional Digital Image Correlation

open access: yesMetrology and Measurement Systems, 2016
Among the full-field optical measurement methods, the Digital Image Correlation (DIC) is one of the techniques which has been given particular attention. Technically, the DIC technique refers to a non-contact strain measurement method that mathematically

Development of a Low-cost Digital Image Correlation System to Evaluate the Behavior of Polymers at Large Deformation

open access: yesChemical Engineering Transactions, 2019
Among the main optical methods digital image correlation (DIC) can be highlighted. Although DIC development is relatively recent, the advantages offered by this method make it equally competitive with other classical optical techniques that suffer from ...
