Abstract

Abstract

In this paper, we measured the blast overpressures of TNT, SEFAE and DEFAE using a pressure measuring system and pressure transducers installed in the free field and on the ground. The data obtained were analyzed and fitted with the blast overpressure development formulas for three explosives. The results showed that the average TNT equivalence of DEFAE in the free field and on the ground were 60% and 69% bigger than that of SEFAE respectively, suggesting that the power of DEFAE was bigger than that of SEFAE. For each of the three explosives the overpressure measured was 10% lower than that on the ground due to the reflection wave generated by the ground. In the actual test, a fixed correction factor needs to be adopted. These results may add to analysis of small quantity of FAE and traditional explosives and serve as reference for the investigations of the blasting power of FAE.
