摘要：

The ballistic performance of bilayer silicon carbide/aluminium (SiC/Al) armour is assessed and compared with the alumina/aluminium (Al2O3/Al) armour using numerical analysis. For the numerical simulation of impact phenomena, ANSYS/AUTODYN software and phenomenological material models are used. The phenomenological models are JH-1 and JH-2 for brittle materials such as silicon carbide and alumina respectively and Johnson Cook (JC) model for ductile materials such as steel and aluminium. This study results shows that the ballistic performance of SiC/Al armour is higher than the Al2O3/Al armour and also SiC/Al target made severe damage to the projectile. The failure modes of these armours against blunt and ogive nose projectile are also evaluated. (C) 2017 The Authors. Published by Elsevier Ltd.
