    Abstract
  • The stress-strain curves of the -zirconium which strain rate ranges from 3.310-4 s-1 to 1.5103 s-1 under room temperature were obtained, and the parameters of Johnson-Cook model were determined through these experiments. The computed free-surface velocity profiles using dynamic damage and fracture model consist with the experimental measurements at 4.3 GPa and 5.1 GPa peak pressure. The comparison indicates that the determined dynamic parameters of -zirconium are valid.
