The behaviors of dynamic damage and fracture of D6A, 921, 45 steels were studied via symmetric impact experiments. Using the double wave structure of the free-surface velocity profile and the material longitudinal elastic wave speed at room temperature, we obtained the D-up Hugoniot relations for the three steels. The Hugoniot elastic limits and spall strengths of the three steels were also obtained. A new simple phenomenal equation for describing the evolution of damage was proposed, with which the experimental spall processes were simulated.
