Web17 de mar. de 2024 · We present our discovery of switchable high explosives (HEs) as a new class of energetic material that cannot detonate unless filled with a fluid. The performance of fluid-filled additive-manufactured HE lattices is herein evaluated by analysis of detonation velocity and Gurney energy. High explosives (HE, or high order explosives) are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocityhigh explosive is in contrast with the term low explosive, which explodes (deflagrates) at a … Ver mais An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light Ver mais Commercial The largest commercial application of explosives is mining.

Web8 de fev. de 2024 · The integration of nanostructured materials in defense systems is expected to improve their performance in terms of power, safety, and reliability. That is why considerable research effort has been undertaken by major military powers worldwide in this domain. The first important step was to develop the production capacities of organic … In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. Current in-use standard methods of mechanical (impact and friction) senstivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type, go/not go criteria, and the statistical analysis of results.
WebAn explosive that is formulated with one or more high explosives that in their pure form have a vapour pressure of less than 10-4 Pa at a temperature of 25°C, is formulated with a binder material, and is, when mixed, malleable or flexible at normal room temperature.
WebAn experimental study of the personnel protective capability of a proposed high explosive material test laboratory using a one-eighth-scale model is summarized. Various configurations of the scale model were tested against internal blast loading over a range of scaled explosive charged weights.
