摘要
进行冲击波对碰加载简易平面金属Sn和W样品实验,采用X射线照相和激光干涉测速系统进行联合诊断,给出了2种材料冲击波对碰区表面微喷及主体破碎物质的直观图像,研究了Sn和W样品对碰区动力学行为,并比较分析2种材料对碰区特征的异同,给出了定性物理解释,实验结果可为爆轰波对碰加载下材料动力学特性的理论研究提供数据支撑。
In th detonation wav surface ejecta a haviors of Sn a provide signific collision of hea paper, dynamic behaviors of metal materials driven by collision of head-on sliding es were diagnosed with pulsed X-ray radiography and DPS, the physical images of free nd body fragmentation on Sn and W were obtained, the difference in the dynamic be- nd W was analyzed, and its qualitative physical analysis was discussed. The results ant experimental data for the study of dynamic behaviors of metal materials driven by d-on sliding detonation waves.
