AbstractWhen an impactor strikes a body at hypervelocities the momentum transferred to the impacted body is greater than the initial impactormomentum. This effect is due to the crater ejeeffect is referred to as momentum enhancement. The small amount of data on this question implies that there is a scale effect that is, asthe projectile size increases there is an increase in the imparted momentum beyond that anticipated due to the increase in projectile size.Recently, experimental data was gath ...
