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.

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 ...

Stereo digital image correlation: formulations and perspectives
Comptes Rendus. Mécanique, 2021 A literature review regarding functionals used in stereo digital image correlation (SDIC) is presented. A suitable functional for performing data assimilation, in the sense that all available information at all times is wisely taken into account, is also

Axial Force Measurement Using Digital Image Correlation
Nihon Kikai Gakkai ronbunshu, 2022 As a simple and highly accurate axial force management method during manufacturing and maintenance of bolt-tightened structures, we examined a method to calculate the axial force from images of the bolt head. In this method, the axial force is calculated

Time‐resolved integrated digital image correlation [PDF]
International Journal for Numerical Methods in Engineering, 2015 SummaryThis paper discusses a method that provides the direct identification of constitutive model parameters by intimately integrating the finite element method (FEM) with digital image correlation (DIC), namely, directly connecting the experimentally obtained images for all time increments to the unknown material parameters. The problem is formulated
