Abstract

It is necessary to determine the quantitative relation between the local normal detonation wave speed D_n and the total curvature κ when detonation shock dynamics (DSD) is used to study nonideal detonation. We extended our work on the D_n(κ) relation of HMX/TNT rate sticks from the RDX/TNT rate sticks. The D_n(κ) relation of HMX/TNT rate sticks in the different mixing ratios was analyzed, and the D_n(κ) relation was compared between the RDX/TNT explosives and the HMX/TNT explosives. Results show that the D_n(κ) curves of RDX/TNT explosives were subjacent on the D_n(κ) curves of HMX/TNT explosives at the same ratio. As the TNT percentage added, the D_n(κ) curves of RDX/TNT and HMX/TNT explosives were moved down. The D_n(κ, R_t) law was induced from the relation of D_n(κ) by introducing into the variable R_t. The D_n(κ, R_t) law could not only reduce the number of experimental calibration, but also meet the simulation precision of DSD method.
