At first in the condition of low - velocity impact it is discussed with the formation of ceramic smash cone angle on the base of quasi - statistic hertz and 3 a 6 y a c - theory . then using spherical stress wave reflection and transmission theory under the state of medium - high velocity the formation of spot in the ceramic back . finally the damage mechanism of ceramic suffered by the high impact is simply discussed 首先，在低速撞击的条件下，基于准静态hertz的理论与萨布斯基理论，分析了陶瓷破碎锥角的形成；其次，在中高速撞击条件下，利用球面应力波反射迭加理论，分析了陶瓷背面的层裂的形成；最后，简单讨论了高速撞击下陶瓷的破碎机理。
