摘要

摘要: 在一维应变冲击加载条件下，采用两个石英压力传感器进行了双值应力历史测量，对非晶态碳材料的动态响应特性进行了分析研究。研究结果表明，非晶态碳材料的冲击响应是简单稳定的，在试验冲击应力范围内为非线性弹性响应，Hugoniot曲线呈上凸的，表明材料内部传播的不是一个冲击波而是一簇压缩波，因此可采用特征线方法来解该冲击波问题，并用Riemann积分法对冲击应力过程进行修正，得到材料更精确的Hugoniot方程。还采用COPS程序对该材料的冲击响应过程进行了数值模拟，数值模拟曲线与试验曲线是很吻合的。表明采用Riemann积分法处理是合理的，此方法可以在VISAR测量中得到应用。

Abstract: The shock impact experiments of vitreous carbon under uniaxial strain were conducted on a keyed light-gas gun. With two X-cut shorted quartz gauges assembled on impactor and target the two stress histories were recorded and used to analyze the dynamic response of vitreous carbon up to 3.7 GPa. Based on the theory of characteristic line and Riemann integrate method, the more reasonable and precise stress histories in shocked state have been corrected, the constitute model of vitreous carbon under shock loading is obtained and used in the COPS simulation code. The simulated stress profiles are agree with the experimental ones quite well.
