Abstract:
The constants in the const itutive equation of granular material have been determined according to the experimental results and analyt ical formulas based on shock polars. The numerical invest igations on interact ions of shock waves with air/ granular interface were carried out by using the const-i tut ive equat ion. The calculated flow fields induced by the interact ions are in good agreement w ith that show n by experimental photographs recorded by the shadow graphs and the pulsed X- ray shadow graphs with t race particles. Effects of the strength of shock waves and the material density of particles on f low fields were discussed.
