The projectiles were fired against the armours at about 1250 m/s. The deformed configurations of the projectiles and the targets were examined after the experiments. The impact experiments were numerically modelled using the AUTODYN-2D program. A time- dependent fracture model for ceramic material previously presented by the authors was implemented in the computer code, in order to represent the ceramic tile behaviour under impact conditions. The results of the numerical calculations were compared with the experimental obser
