Abstract

Digital image correlation (DIC) techniques have been used in forming limit tests to obtain forming limit strains and many different methods have been proposed to determine the onset of localized necking in order to improve the accuracy of forming limit curves in recent ten years. In this work, necking limit strains of a PLC material (AA5182-O) was determined by the DIC strain rate contours as well as the existing DIC methods in the literature. The effect of PLC band propagation on identification the onset of localized necking was discussed.
