• Estimation of Elastoplastic Parameters via Weighted FEMU and Integrated-DIC (2015, methodology): “This method often yields results with less uncertainty than those post-processing measured data [47, 36], as it allows to perform the measurement and identi cation of the sought parameters in one step instead of two.”
• Application of Digital Image Correlation (DIC) in Dynamic Notched Semi-Circular Bend (NSCB) Tests (2014, methodology): “Integrated DIC [31, 32] were also developed to directly output the crack-tip position and the corresponding SIF.”
• Shape, displacement and mechanical properties from isogeometric multiview stereocorrelation (2015, methodology): “To mention but one example, nite-element based DIC procedures were proposed ten years ago [5, 32, 4] and have been used in various applications since then [22].”
• The Grid Method for In‐plane Displacement and Strain Measurement: A Review and Analysis (2016, background): “Assessing the errors made while measuring displacement or strain components is addressed in several papers on DIC, see [149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 100, 101] for instance.”
• Comparison of Local and Global Approaches to Digital Image Correlation (2012, methodology): “To evaluate the resolution1 of the developed technique, since the un-noised reference is not known, the noise is assigned to the deformed picture with a variance 2σ 2, where σ 2 is the variance of Gaussian white noise [32].”
• Identification of a crack propagation law by digital image correlation (2012, positive): “To evaluate directly ( i.e. with no post-processing of the measured displacement field) the SIF and thus the crack tip location and other relevant mechanical parameters, so-called “integrated approaches” of DIC (or I-DIC [29, 30, 5, 28]) can be followed.”
• Voxel-Scale Digital Volume Correlation (2011, methodology): “ber of voxels in the considered finite element, p the physical size of one voxel, A a dimensionless constant dependent on the interpolation function [33, 43 ].”
