Abstract. For many years now, explosive reactive armour (ERA) has been
well proven in reducing the penetration of shaped-charge jets into
MBT hulls. This kind of appliqué protection, however, is more
suited to heavy vehicles than lightweight armoured vehicles. A numerical
study using the explicit non-linear transient dynamic finite difference code
AUTODYN-2D has been undertaken to examine the effect of a
rear plate from an explosive reactive armour impacting lightweight armoured
vehicle hulls at normal incidence. Four thicknesses of explosive reactive
armour plate impacting high hardness steel armour and an aluminium
alloy (7039) armour were simulated. The deformation of the vehicle
hull and the measured strains are reported indicating critical areas
around the fixings and the central region of impact. These
results make clear the need for care in applying explosive
reactive armour plates to lightweight hulls.
