 | We report on the measurements of the shock equation of state (Hugoniot) of an Al/Fe2O3/epoxy composite, prepared by epoxy cast curing of powder mixtures. Explosive loading, with Baratol, trinitrotoluene (TNT), and Octol, was used for performing experiments at higher pressures, in which case shock velocities were measured in the samples and aluminum, copper, or polymethyl methacrylate (PMMA) donor material, using piezoelectric pins. The explosive loading of the metal donors (aluminum ... |

|
| This report documents the design at Sandia National Laboratories (SNL) of the largest known conical shaped charge (CSC). This CSC was designed specifically to generate a very large hole diameter and a substantial jet penetration depth in hard rock and concrete structures as part of the Cruise Missile Program. The charge will fit in the existing volume between the missile body and the PEN-X penetrator weapon that it carries. The ... |

|
| Testing and training ranges are essential to maintaining the readiness of the Armed Forces of the United States and Canada. Recently, concerns have arisen over potential environmental contamination from residues of energetic materials at impact ranges. The current state of knowledge concerning the nature, extent, and fate of contamination is inadequate to ensure sound management of ranges as sustainable resources. This project was designed to develop techniques for assessing the ... |

|
| The production and usage of high explosive compounds such as 2,4,6- trinitrotoluene (TNT), hexahydro-l,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-I,3,5,7-tetranitro-1,3,S,7-tetrazocine (HMX) have resulted in their release in the environment. These compounds pose potential harm because of their reactivity and effects on health. Agencies that use high explosive compounds are working to better understand the physical and chemical properties surrounding these explosive compounds to include their fate and transport, effects on health, and remediation ... |

| One-Liter Test: A Mid-Scale Safety Characterization Test For Melt- Castable Explosives |

|
| The One-Liter test was developed as a mid-scale safety characterization test specifically for use with melt-castable explosives. It is a one-dimensional test carried out under relatively unconfined conditions that are similar to those encountered in melt casting operations. The test allows the researcher to assess the response of the explosive to a controlled thermal stimulus under laboratory-like conditions and, more importantly, to determine its critical temperature. The latter is defined ... |

|
| Mixtures of 2,4,6-trinitrotoluene (TNT) and the nitramines cyclotrimethylenetrinitramine (RDX) and cyclotetramethylenetetranitra-mine (HMX) are used in a variety of high-explosive formulations, such as Composition B (RDX/TNT) or Octol (HMX/TNT). There has been much recent interest in the use of supercritical fluid (SF) CO2 technologies for the processing and/or demilitarization of energetic materials. The solubility of RDX in neat CO2 was measured over a temperature and pressure range of 303-353 K (30 ... |

|
| This is the final report of the disposal of laboratory quantities of energetic materials. SRI examined the use of very hot water as a medium for safe and complete disposal of energetic materials. The temperatures Os the study were in the range of 200 - 350 deg C. 0ne of the tasks dealt with the hydrothermolytic destruction of a range of pure energetic materials and various energetic formulations. The program ... |

|
| Experimental data for several reactive (explosive) and inert materials have been examined, and the important particle velocities (V1 and VF) were computed. The associated shock velocity (Usf) and shock pressure (Psf) were also calculated to facilitate comparison with experimentally observed reactive or anomalous events. The explosives analyzes are: pressed TNT, PBX-9407, octol, pressed PETN, and crystal PETN. Three rather diverse inert materials are considered. They are: poly pyromellitimide (PPMI), iron, ... |

| Analytical Assessment of the Suitability of a Liquid Explosive Substitute for Shaped Charge Testing |

|
| In this analysis, a 95% nitromethane (NMe) and 5% diethylamine (DEA) liquid explosive is substituted into a BRL 3.3 inch 42 degree conical copper lined charge. The original charge is Octol loaded. Since NMe is less energetic, it is expected to give a reduced jet tip velocity, less jet mass, and lower overall jet kinetic energy. This would naturally follow from the use of a lower energy density explosive. The ... |

|
| Analytical studies of the collapse of (1) hemispherical, point initiated, (2) hemispherical, surface initiated and (3) conical, point initiated warheads, using the HELP and EPIC hydrocodes predicted tubular or layered jets. Each shaped charge geometry studied revealed a different flow pattern during the jet formation and collapse process. The analysis further suggested that the liner flow process could be verified experimentally by collapsing stratified, bimetallic liners in actual warheads. Experimental ... |

| Authors:
B. M. Simmons; ARMY BALLISTIC RESEARCH LAB ABERDEEN PROVING GROUND MD
|
 | The HEMP code was used to model shaped-charge collapse and jet formation processes for several charge configurations. Jet characteristics were determined by coupling the HEMP code output to the jet formation theory of Birkhoff, MacDougall, Pugh, and Taylor. A new feature of this study with HEMP is an explicit rule for determining when a liner segment collapses into the jet flow. Radiographs of shaped charges tested at BRL were compared ... |

|
| The process of exudation of confined explosives containing TNT, and the adverse consequences and interactive effects in munitions is described. A 70 C test for prescribed times to measure the exudate from explosives under confinement is described and has been tested, as amended, for reproducibility by the Prins Maurits Laboratorium, The Netherlands. Since exudation values for TNT of a given set point and of various manufacture vary, three descriptive exudation ... |

|
| A study of explosive drivers for use in short term experimental ballistics programs requiring hypervelocity launch capability for high density, high L/D projectiles has been carried out. The study focused on the problems associated with the application of explosive drivers as a possible simple expedient in ballistics programs requiring a small number of test shots. Since prior use of explosive drivers has not dealt with the launch of high density, ... |

|
| There is presently only one domestic facility for production of RDX and HMX. In order to increase RDX/HMX production capability as well as to alleviate dependence on a sole source supply, the initial phase of design for an RDX/HMX Expansion Facility was conducted. The proposed RDX/HMX Expansion Facility at Holston Army Ammunition Plant (HAAP), Kingsport, Tennessee, called Plant X, consisted of two explosives manufacturing lines producing the end products - ... |
