The recompression phenomena have been found in the particle velocity histories of alumina specimens while the impact pressure between 7GPa-8GPa. From the point of view of phenomena, the recompression signals in terms of free surface particle velocity occurring in alumina ceramics under shock-loaded were similar to those in glass where failure wave has been widely verified.(4)The modified form for the Hugoniot Elastic Limit was given associated with

得到了A95陶瓷采用Drucker-Prager准则修正公式计算的σHEL值，并与实验得到的σHEL值进行了比较；(5)采用ANSYS/LS-DYNA有限元分析软件对冲击压缩下氧化铝陶瓷动态力学性能进行了模拟分析，数值模拟结果与实验结果吻合较好，数值模拟结果表明JH-2材料模型能够较好地模拟陶瓷的物理力学性能。
