Abstract:This article describes a convenient method to quantify the dynamic J‐R curve through digital image correlation (DIC). The DIC approach, verified through numerical and experimental results for single edge notched bend (SE(B)) specimens, quantifies the dynamic J‐R curve during the drop‐weight tearing test (DWTT). The proposed method enables consistent measurement of the J‐integral and the amount of crack extension solely from the DIC measured displacement on the specimen surface, which facilitates direct compari… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
