摘要
采用一种改进后的前照明分幅摄影技术,研究了45号钢管在三种不同猛度炸药加载下的膨胀断裂行为,得到了与材料动态断裂行为有关的一些参数值。还结合壳体材料性质及载荷强度,对破片的断裂特征及尺度分布进行了讨论。
This paper presents expansion and fragmentation behaviour of the 45 steel cylinders loaded with three different brisance explosives,a renewed front-lighting methord is employed in the experiment. Some dynamic fracture parameters are given. The relations between material characters combining with loading-strength and fragment mass distribution are also discussed.
