The govering equation of hydrodynamics are discreted over time. Using a VISAR trace as “initial conditions”, they are numerically integrated backwards in space. A detail analysis shows good precision has gotten. The traced pressure load history at load surface is consistent with Bai’s results. The deduced stress-strain behavior of copper agrees well with the isentropic used in Bai’s code.
