摘要:

锡试样在相同条件下用发散的高爆炸冲击波冲击损坏/熔化。质子射线照相图像和速度测量数据从实验与七个不同的锡试样的不同厚度进行了分析。用相同的样本进行比较实验,使我们能够区分可重复和随机特征。主要碎片的速度和速度是试样厚度的确定性函数;随机差异仅在小范围内存在。的领先层和主要的碎片的速度不同的试样厚度,这可能是有关的金属层的分离能量的相同的值。

英文摘要:

Tin coupons were shock damaged/melted under identical conditions with a diverging high explosive shock wave. Proton Radiography images and velocimetry data from experiments with seven different tin coupons of varying thickness are analyzed. Comparing experiments with identical samples allowed us to distinguish between repeatable and random features. Shapes and velocities of the main fragments are deterministic functions of the coupon thickness; random differences exist only at a small scale. Velocities of the leading layer and of the main fragment differ by the same value independently of coupon thicknesses, which is likely related to the separation energy of metal layers.
