Abstract:The aim of this paper is to investigate fundamental damage behaviour of metallic materials such as aluminum, carbon steel and titanium, which have typically different crystal structures, by the single impact from low velocity to hypervelocity. Impact tests by a WC ball were performed on the three metallic materials at various impact velocities and at normal angle. Both two-stage light gas gun and ordinary air gas gun were used in this study. Indentation shapes on a cross-sectional surface and the ratios of cra… 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.
