Abstract：The impact tests and theoretical studies were carried out to study the ballistic performance of monolithic steel plates, and the influence of the thickness of plates on the ballistic performance was revealed. In general, good agreement was obtained between the predictions from analytical model and the experimental results. Results showed that the theoretical model can be used to predict the ballistic limit velocities of plates under the impact of projectiles. Moreover, the energy absorption of plastic deformation of plates was discussed and accounted for the effect of strain rate of plate material, including local and global deformation energy absorption. An amendment function was used correct to the thickness of plate in the case of plate impacted by blunt-nosed projectile.
