| Abstract: | With respect to an actual experiment, finite element simulation using LS-DYNA3D is performed to investigate the responce of a ceramic integral armor penetrated by high-velocity long rod of tungsten alloy. The main penetrating patterns are obtained and discussed. The simulateel results are in good agreement with the experimental results. It gives useful insight into the investigations on the protective composite systems and rod projectiles. |
