The behaviour of armour plates subjected to
impact by projectiles for velocities including and exceeding
ballistic limits, has been investigated primarily using
the following approaches: (a) controlled experimentation 1-6,
(b) estimation of residual velocity and ballistic limit
with the aid of semi-empirical and limit-state solutions2,7,8,
and (c) finite element-based contact-impact analysis9-19.
The third approach, if properly validated, could be
considered as the most potent approach for predicting
ballistic limits of armour plates and for designing
optimised as well as innovative solutions.
