ABSTRACTguns. This has led to a consideration of the effects of velocity on efficiency of long rod penetrators, with the A new type of experiment has been developed to results shown in Figure 1, which is based on the subject rods to dynamic transverse impact similar to that penetration formula for tungsten heavy alloy (WHA) encountered in attack of modem armors. Two tungsten rods found in Subramanian et al. [1]. The evident alloys with five different surface finishes were examined, conclusion from the figure is that, for RHA penetration It was found that there were two failure modes: one with a fixed L/D WHA rod, the most efficient impact involved transverse fracture that initiates from surface velocity is about 2.2 km/s. flaws. The other was a consequence of gouge instability on the sliding surface. Polishing suppressed the first 1.6 mode and enhanced the second.
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.
