Effect of Subset Size and Gage Length for Measurement Accuracy in Digital Image Correlation

The measurement accuracy and the spatial resolution of displacements and strains by digital image correlation method (DIC) is investigated. Displacements of the in-plane rigid body rotation are measured by DIC using various subset sizes. Displacement gradients are calculated using local least square...
