The flow fields both in gas and dusty bulk and the entrained dust cloud induced by interact ions of shock waves and a surface of dusty bulk were record, by means of shadow g raphs and pulsed X ray shadow graphs w ith t race part icles. Incident shock angles, t ransmitted shock angles and turning angles of material surface can be measured from the g raphs. Based on experiments and shock polar analysis, the const itutive equat ions of granular material w ere determined and calculations were performed. The measured and calculated result s were in good ag reement .
