Tóm tắt

 In this paper, duplicate cylinder tests (CYLEX) have been run on PBX 9502 and LX-17. The 95 % error in the absolute value of the derived detonation energy density is about �1 % whereas the 95 % error of the difference error is �0.5 % or better. The analytic model has been upgraded with a better strain description. The effect of the air gap between a pressed solid explosive and the inner copper wall has been measured and modeled. An off-center effect has also been seen. Density effects on the energy density from 1.82 to 1.92 g cm<
