摘要：

The performance of composite ceramic armor penetrated by rod projectile was studied by both numerical simulation and experiment. The penetration and damage mechanisms of the projectile-armor after high-speed collision were also observed by high-speed photography. The experimental results showed that the ballistic performance of composite ceramic armor was highly affected by the density, hardness and toughness of bulletproof ceramic. The flow stress of the failed bulletproof ceramic is not only related to the pressure but also related to the strain rate. The phenomenological method based on Bodner-Partom ceramic model was introduced to derive the growth rate of damage. Numerical simulation results show good agreement with the experimental results.
