Optical Properties of K9 Glass under Shock Loading

National Key Laboratory of Shock Wave and Detonation Physics, Institute of Fluid Physics, CAEP, Mianyang 621999, China

摘要

摘要: K9玻璃常作为冲击载荷下失效波(破坏波)萌生机制和脆性材料动态断裂特性的研究对象，而当作为冲击窗口材料时，由于冲击压力范围限制，其光学特性研究常被忽略。通过平板撞击实验，结合激光多普勒测速系统(DPS:Doppler Pin System, 激光波长为1 550 nm)，获得了冲击波传播过程中不同光学测试界面运动的速度历史。通过分析原始干涉信号和界面速度剖面的时间对应关系，获得了K9玻璃保持冲击透明性及弹性响应的压力范围。研究结果表明，当冲击压力低于8 GPa时，K9玻璃能保持良好的光学透明性，其动态折射率随密度的变化呈典型线性关系。

Abstract: K9 glass is often used to study the generation mechanism of failure wave and the dynamic fracture property of brittle materials under impact loading.However, the research on the optical property of K9 glass is often ignored due to the impact pressure limit.In this work, through the plane impact experiment combining the Doppler pin system (DPS) with the laser wave length of 1 550 nm, the velocity history of different optical testing interfaces during the spread process of the shock wave was obtained.Based on an analysis of the temporal correspondence between the original interference signal and the interface velocity profile, the pressure range within which the K9 glass maintains impact transparence and elastic response was achieved.The results show that when the impact pressure is less than 8.0 GPa the K9 glass can maintain good transparent property, and its dynamic refractivity changes linearly with the density.
