Determining the stress-strain behaviour at large strains from high strain rate tensile and shear experiments (2011, methodology): “Furthermore, interpretation of the DIC results is not straightforward, errors can easily be introduced [18, 19].”
Precise determination of the Poisson ratio in soft materials with 2D digital image correlation (2013, background): “A large strain window can increase the accuracy of the calculated strains but it may also mask inhomogeneities [5].”
Theoretical Analysis on the Measurement Errors of Local 2D DIC: Part I Temporal and Spatial Uncertainty Quantification of Displacement Measurements (2016, methodology): “Those researches are generally performed on simple tests, such as rigidmotion, 1st-order deformation, 2nd-order deformation, and sinusoidal deformation [22, 23, 25, 29, 34–38], or on images deformed by Finite Element Analysis (FEA) deformation fields [39, 40].”
