Effect of the order of plates on the ballistic resistance of ductile layered shields perforated by nonconical impactors

G. Ben-Dor, A. Dubinsky and T. Elperin

Vol. 1 (2006), No. 7, 1161–1177
Abstract

In our previous studies using the two-term impactor-shield localized interaction model, we derived the rule determining the order of the plates with different mechanical properties in a multilayer shield that yields a maximum ballistic limit velocity against conical impactors. In the present study we show that this rule is valid also for ogive-shaped, nonconical impactors.
