Based on the simulation law established here, prototype experiments and model experiments with the simulation ratio of 1.33 are designed, and the penetrating armour experiments with 45 # carbon steel plates are separately conducted. By means of data processing of experimental results, it is concluded that EFP penetrating armour simulation law established is tenable.展开更多
