【Abstract】 By using LS-DYNA code(a general purpose finte element code),the process of different dimensions of rods impacting armor plate are simulated with different velocity at a small obliquity.Finally,the limit penetration velocity of different rods was obtained.The simulation results can provide important foundation and reference for the design of discrete-rod warhead and damage evaluation.更多还原
