Abstract:Results of interaction of a high-velocity annular steel impactor with a flat steel plate are reported. An annular crater is formed on the frontal surface of the plate. On the backward surface of the plate, the material is spalled in the form of a solid quasi-disk whose diameter is almost twice the outer diameter of the annular impactor. This observations shows that annular impactors are more hazardous than solid impactors (with an identical velocity and outer diameter).Keywords: high-velocity impact, annular i… 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.
