Numerical simulation of shock wave

In this paper, different numerical simulation models of shock wave are established according to the different nature of objects. Simulation model under impulse criterion is established based on the scaling law which is suitable for diffraction targets. Simulation model under overpressure-and-impulse criterion is set up with the method of extracting the shock wave parameters from whole-scale space and then calculating partially. Simulation model of shock wave entering into structure through openings is also established which will be the basis for the research on destroy effect within limit space. (authors)
