The comparative effect of HMX content on the detonation performance characterization of PBX 9012 and PBX 9501 high explosives

Validation of a detonation product equation of state for an insensitive high explosive via slab geometry expansion tests

“…The majority of these involve hydrodynamic simulations based on programmed burn (PB) calculations, where, for timing, the normal component of the detonation velocity is assumed constant, and where comparisons of PB simulations with experimental Cu wall expansion data are made at a discrete number of expansion volumes. 4,6,10 In recent work, 9,[11][12][13] the present authors have developed an advanced methodology for calibrating the JWL equation of state of detonation products via CYLEX tests. It involves the use of a PB approach employing accurate detonation timing calculations via velocity-curvature detonation shock dynamics (DSD) modeling, combined with velocity-adjusted JWL EOS hydrodynamic simulations of the expanding HE detonation products driving the CYLEX Cu wall motion.…”

Detonation Performance Experiments, Modeling, and Scaling Analysis for Pentaerythritol Tetranitrate (PETN) High Explosive

“…Our model analysis uses a modern programmed burn (PB) methodology [9][10][11] for calibration of PETN at 1.65 g/cm 3 . Our chosen methodologies to represent the sub-scale timing and energy release modeling components of this PB method are described in the following sections.…”

“…Our iterative hydrocode-based process solves the energy release and products EOS parameters of this model [9][10][11] and is constrained by the PDV wall motion records. This process requires repeated simulations of the CYLEX test geometry and the extraction of the simulated wall velocity trace for comparison to the experimental data.…”

Preparation of μ-HMX/C-Based Composite Energy Composite Microspheres by Microdroplet Technology

“…As a core component of military equipment, energy-containing materials have been transformed from high performance to practicality and safety, and safety has become an important criterion for measuring the performance of weapons. Improved formulation and passivation treatment is one of the important methods to improve the safety of weapons. − High-energy ammonium nitrate explosives 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (HMX) are widely used as the main charge of conventional weapons combat sections, but they suffer from problems such as irregular crystal morphology, nonuniform size distribution, and crystal defects . In the continuous production process, the morphology size and crystal quality of explosives are usually affected by factors such as the mixing efficiency of raw materials, which makes it difficult to obtain high-quality crystal products .…”
