数值模拟
The numerical simulation and the experiment of the effects of the enhanced PELE of reactive materials on a metal plate are carried out to investigate the influence of the ratio of length to diameter, the thickness of the plate and the impact velocity on the terminal effects. It is shown that the influence of the ratio of length to diameter on the lateral efficiency and the deflagration efficiency of the enhanced PELE of reactive materials is limited, but the damage effect will decline if the ratio of length to diameter is too small, With the speed of 800 m/s, the damage effect of the enhanced PELE of reactive materials on the plate in a range of 10-15 mm is better; The enhanced PELE of reactive materials performs better for intercepting a high speed target.
