摘要 利用三维非线性动力有限元程序LS-DYNA3D,建立了高速钨质长杆弹对多层陶瓷装甲侵彻的有限元分析模型,描述了侵彻全过程的有关物理和力学现象,对进一步研究陶瓷装甲防护及弹体侵彻性能具有一定的参考价值。 Finite element simulation using LS-DYNA3D is performed to investigate the response of a ceramic integral armor penetrated by high-velocity long rod projectile of tungsten alloy. The main penetrating patterns are obtained and discussed. It gives useful insight into the investigations on the protective ceramic systems and rod projectiles.
