Tungsten based heavy alloys (WA), used as penetrators, constitute a major threat. An experimentaland numerical investigation was performed to study the ballistic performance of aluminatile-based composite targets in an effort to generate data for certain high performance WAprojectile. The experiments were conducted using tungsten-alloy projectiles of25x137mmAPDS-T (M791) at a striking velocity of 1260 m/s. This heavy metal projectile hashigh strength and is relatively ductile. It is, therefore, difficult to apply on the projectile modelstructural cracking, breakage or fragmentation, even upon oblique impact that generatesasymmetric forces. In order to find an effective mechanism that will defeat such projectiles, it isnecessary to develop numerical models simulating the behavior of the projectile during thepenetration process. The ceramic tiles used for this study were backed by 80 mm RHA steelblocks. The residual depth of penetration in the RHA block was used as a reference measurefor the resistance of the ceramic targets to ballistic penetration. This study consists of threephases: the first examined the influence of confinement of the ceramic tiles on the ballisticperformance. The second examined the efficacy of adding a cover plate. The third examined theeffect of laminated structures on the effectiveness of ballistic ceramic tiles. In general, each ofthese configurations is known to be effective in enhancing the resistance of the ceramictarget. For a reference to the simulations, several ceramic penetration theories which areavailable and published in the literature, Refs. [1]-[5], were used and discussed.
