摘　　要：针对陶瓷材料、金属材料的动态损伤本构模型的基本理论进行了阐述。在此基础上,采用有限元数值分析方法对基准铝靶和蓝宝石单晶/2024航空铝复合靶侵彻深度试验进行了仿真。为了验证所建立模型的可靠性,开展了蓝宝石单晶/2024航空铝复合靶侵彻深度试验。对仿真结果与试验结果进行了对比,结果表明建立的数值模型能较好地反映蓝宝石单晶材料的抗弹特性。This paper discussed constitutive models of ceramic material and metal material.On this basis,finite element numerical analysis method was used to simulate the penetration depth test of the reference target and the sapphire single crystal/2021 aviation aluminum composite target.In order to verify the reliability of the established model,the penetration depth test of the sapphire single crystal/2021 aviation aluminum composite target was carried out.The simulation’s results were compared with the test’s results,and the results showed that the numerical model could reflect the elastic properties of sapphire material well.
