The fundamentally-derived determination, prediction, validation, and accurate tabulation of the high-pressure response of materials are critical in the assessment of stockpile performance. High-pressure properties of materials can be broadly classified in terms of Thermodynamic properties, Mechanical properties, Electronic and phonon properties and Chemical properties.
Thermal and chemical properties of various forms of energetic materials are studied at high pressures and temperatures, ranging from unreacted high explosives (nitromethane, HMX, PETN, TATB, LX-17, etc.) to reacting (deflagration, detonation, decomposition) systems, to major detonation products (carbon, H2O, N2, CO2) to mixtures of these materials.
An experimental effort to achieve the synthesis and characterization of members of a new class of energetic materials, that are predicted to have energy densities (energy per unit volume) much larger than conventional high performance explosives.
The Earth and neighboring planets are made of relatively simple materials at very high pressures and temperatures. Therefore, the laser-heated diamond anvil high pressure technique provide a unique way to learn about the chemical composition, internal structure, energy balance, magnetism, and the exact states of major constituents in general.
