Abstract

Local strain analyses in a dual phase steel were performed using a digital image correlation (DIC) method in association with Ag nanodot patterning. The optimum size of the nanodots for DIC was estimated from image error analyses. The nanodot patterning sheds light on the DIC for nanoscale local strain analysis due to its many advantages, such as high productivity, large patterning area, easy control of the dot size, and, furthermore, good adhesion.
