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

On image gradients in digital image correlation
International Journal for Numerical Methods in Engineering, 2015 SummaryIn digital image correlation (DIC), the unknown displacement field is typically identified by minimizing the linearized form of the brightness conservation equation, while the minimization scheme also involves a linearization, yielding a two‐step linearization with four implicit assumptions.

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
