(Color online) Three velocities change on the free surface particle velocity profile. Circle 1 shows the “slow-fast effect,” circle 2 shows the “fast-slow effect” or “shoulder effect,” and Circle 3 shows the “overshoot effect.”

(Color online) The time-based correlation between stress distribution inside the sample and the free surface particle velocity profile. (a) x-t diagram for symmetric impact at high pressure. (b) The stress of the candidate spall plane. (c) The free surface velocity profile of the sample with damage.
