“…A series of double shock initiation experiments [12,13] on an HMX-based explosive EDC37 (91% HMX and 9% binder) revealed more interesting facts. In the first set of experiments (experimental shots 1175/1176), the explosive was subjected to a 2.87 GPa shock followed by a 6.2 GPa shock.…”

“…The pressure history was measured at various gauge points inside the explosive; the gauges were 0.5 mm apart. The series of double shock initiation experiments [12,13] on an HMX based explosive EDC37 was chosen for the simulation and validation of the newly implemented model, because these experiments reveal a broader range of features involved in the shock desensitization process of an explosive. Figures 10 and 11 in reference [13] are experimental particle velocity histories at different gauge positions inside the EDC37 explosive for shots 1175/76 and shots 1191/92 respectively.…”

Figures 10 and 11 in reference [13] are experimental particle velocity histories at different gauge positions inside the EDC37 explosive for shots 1175/76 and shots 1191/92 respectively. For simulation of these reported experiments [13], two pressure pulses, where the second pressure pulse was delayed by the experimental time for each shot, were applied on one side of the explosive as initial conditions, as shown in Figure 3.…”

Abstract:Desensitization caused by pre-shocking in heterogeneous explosives is discussed. The aim of this study was to find a simple numerical model that could reproduce the important features of previously reported shock desensitization experiments. After reviewing the previous experimental results and modelling efforts, an extension of the Lee-Tarver reactive flow model is proposed. The proposed desensitization model is based upon the experimentally determined desensitization criteria for explosives. The additional parameters required for this extension can be calibrated by experiment for a typical explosive. The new model has been implemented in the hydrodynamic code LS-DYNA as a user defined equation of state, and is now available to simulate various kinds of situations involving explosives up to the limits and capabilities of LS-DYNA. Desensitization by pre-shocking in double shock experiments, reflected shock and detonation quenching experiments have been studied using the new model, and the results were found to be in qualitative agreement with the experimental results reported in the literature.

Abstract. The shock induced mechanical response of an HMX based plastic bonded explosive (PBX) has been investigated in terms of the shear strength. Results show that shear strength increases with impact stress. However comparison with the calculated elastic response of both the PBX and pure HMX suggests that the overall mechanical response is controlled by the HMX crystals, with the near liquid like nature of the binder phase having a minimal contribution.

One‐dimensional plate impact experiments have been performed to study the double shocks to detonation transition and Hugoniot state in the HMX‐based explosive JOB‐9003. The flyer was a combination of sapphire and Kel‐F, which can pass two different pressure waves into PBX Explosive JOB‐9003 sample after the impact. The particle velocities at interface and different depths in the JOB‐9003 sample were measured with Al‐based electromagnetic particle velocity gauge technique, thus obtaining particle velocity‐time diagram. According to the diagram, the corresponding Hugoniot state can be determined based on the particle velocity and shock wave velocity in the sample. Comparing with sustained pulse experiments, PBX Explosive JOB‐9003 shows desensitization feature due to the pre‐pressed shock wave.
