The measurements of the width of a localized zone on the surface of notched concrete beams under quasi-static three-point bending were performed using the 2D Digital Image Correlation technique. Different image length resolutions, image search patches and distances between search patch centres were tested. Attention was paid to the accuracy and objectivity of surface displacements measured. An original method was proposed to determine the width of localized zones above the notch based on experiments.
