摘　　要：根据已有的实验数据和文献参数,确定了YB-AD90陶瓷材料的JH-2模型参数。采用Autodyn-2D程序,对杆式动能弹侵彻YB-AD90陶瓷复合靶的侵彻深度和动力学侵彻过程进行了数值模拟。研究结果表明,采用的数值模拟方法和陶瓷材料JH-2模型参数合适,模拟结果与实验结果基本吻合,并且能够模拟动态侵彻过程中弹丸头部的形状变化、材料破碎和通道塌陷等重要特征。JH-2 constitutive model parameters of YB-AD90 ceramic were derived from experiments and literatures. The penetration depths and the dynamic penetration processes of rod projectiles into YB- AD90 ceramic targets were numerically simulated using Autodyn-2D. The results indicate that the simulation method and parameters of JH-2 model are acceptable. Some important features in the penetrating processes such as the shape change of the projectile head,the material fragmentation, and the channel-collapse are simulated and discussed. The simulation results are consistent with experimental results.
