    Abstract
  • The line-image VISAR was applied in a detonation experiment, in which a flyer with Zigzag trenches was driven by a divergent detonation wave.The free surface velocity of a 12 mm-long line on the flyer was obtained, and the velocity distribution on the free surface was also recorded at 1, 3, 5 μs after the free surface started moving.Finally, the experimental model was simulated using LS-DYNA program, the results are in good agree with the experimental results, which prove the potential of Line-Image VISAR in heterogeneous experiment.
