Abstract:This work presents a phenomenological model for estimating projectile penetration into granular lightweight expanded clay aggregate often known as Lightweight expanded clay aggregate (LECA). Laboratory scale penetration experiments in the low-velocity regime performed using LECA are presented. A penetration model based on the mass and momentum balances is proposed and the model parameters are derived from the physical behaviour of the penetrated material. It was found that the penetration behaviour predicted b… 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.
