ANSYS/LS-DYNA is used to simulate the penetration process of B900FD - 1 bulletproof armor plate, Comparisons and analysis were made between numerical simulation and experiment results. The numerical simulations shows that the Johnson-Cook constitutive model could simulate the physical and mechanical behaviors of ductile materials under shock-loaded. The ultimate-thickness of B9OOFD-1 bulletproof armor plate under 500m/s impact velocity is analyzed by more numerical simulations. 相似文献
