以侵彻深度(depth of penetration,DOP)实验为基础,利用LSDYNA软件进行数值模拟,对钨合金长杆弹侵彻45钢鉴证靶和约束AD95陶瓷复合靶进行了对比研究。通过数值模拟与实验结合的方法,得到了AD95陶瓷的JH2模型(Johnson—Holmquist ceramic material model)参数;深入分析了钨合金长杆弹侵彻约束AD95陶瓷复合靶侵彻响应过程。
DOP (depth of penetration) tests were performed to study the ballistic penetration charac- teristics of confined AD95 ceramic targets by tungsten long rods. Based on the experimental data, numerical simulations of tungsten long rods penetration into 45 steel and confined AD95 ceramic targets were compared, using LS-DYNA software. The computational results are in good agreement with the experimental results. The material constants of AD95 ceramic were obtained for the JH-2 model. The response of confined AD95 ceramic targets was investigated by finite element simulations.
