A Probabilistic Model of Optimising Perforated High-Strength Steel Sheet Assemblies for Impact-Resistant Armour Systems

Abstract

This paper presents a concept for optimising an assembly of perforated metal sheets with a probabilistic theory, and the results of testing perforated bainite steel sheets with a nanocrystalline structure. The work presented herein was completed with an assumption of applying the perforated sheets in the design of anti-armour-piercing and anti-HEAT armour systems. The theoretical analysis and experimental research were performed for a 7.62x54 mm R API B-32 projectile and a PG-7 rocket-propelled grenade.
