Abstract

Aimed at the fact that 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, steady-state detonation velocities and wave shapes were measured for HMX/TNT cast explosives at mass ratios 60/40, 50/50 and 40/60. Results show that detonation lag z increases with the increase of TNT mass percentage and it decrease with the increase of explosive density; and that with the increase of TNT mass percentage, the slopes of D _n(κ) curves become large and the change rates of the slopes are positive. For reducing the costs of the experiment, the general D _n(κ, R _t) law was induced from the relation of D _n(κ), and the relation of R _t-z-r was obtained by the D _n(κ, R _t) law.
