Abstract. For many years now, explosive reactive armor (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 armored 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 armor impacting lightweight armored
vehicle hulls at normal incidence. Four thicknesses of explosive reactive
armor plate impacting high hardness steel armor and an aluminium
alloy (7039) armor 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 armor plates to lightweight hulls.
