在圆锥头弹体正冲击下薄壁金属圆板破裂模式的实验研究

Rupture of Thin Metal Plates under Normal Impact of Deffernt Conical-Nosed Missiles, An Experiments

报道了四种不同材料的薄金属圆板在不同锥头子弹正冲击下破裂的实验结果 ,实验中测量了薄金属圆板在不同锥头子弹正冲击下的临界破裂速度 ,确定了正冲击下圆板的破裂模式 .

The rupture of a thin metal circle-plate acted by a conical-nosed missile striking at its center is investigated by experiments. The minimum rupture speed (speed for the impact) is measured, and the local damage mechanism at different conditions is discussed.
