Abstract:An impact reaction experiment is conducted with a modified split Hopkinson pressure bar (SHPB) apparatus to study the reaction threshold of aluminum/polytetrafluoroethylene (Al/PTFE) reactive materials under confining pressure. The dynamic compression behavior, impact damage characteristics, and impact reaction threshold of the Al/PTFE reactive material under the confining pressure are investigated. The results have presented that confining pressure makes the specimens suffer triaxial loading and improves the … 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.
