    Abstract
  • Layered plates are normally impacted by ogival, blunt and hemispherical projectiles using a gas gun to investigate the influence of the number of layers on the ballistic resistance and target failure model. The residual velocity versus the initial velocity curves for the projectiles are constructed, and ballistic limit velocities are obtained. Based on the experimental data, the monolithic targets show greater ballistic limit velocity than multi-layered targets. For blunt and ogival projectile, the ballistic limit velocity decreases with increasing of the number of layers. However, for hemispherical projectile, the ballistic limit velocity firstly decreases and then increases with the increase of the number of layers. The influence of layering decreases as the impact velocity of projectile increases.
