Abstract : Experimental and numerical simulations were performed to study the response of different glass targets to impact loading by tungsten carbide projectiles. In most cases the projectiles perforated the targets without significant damage to the projectile. Therefore the investigation concentrated on taking into account the material properties of the targets to analyse the ballistic behavior of glass. Accordingly, the glasses used as target material had very different densities, strengths and speed of sound. The results from experimental and numerical investigations showed that the mechanical properties exhibited by standard glass materials have no significant influence on the ballistic resistance. It was the thickness of the glass targets which in general determined its protective strength.
