    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.
