Parent topics

  • Chemistry [r]: The science of matter, or of the electrical or electrostatical interactions of matter. [e]
  • Demolitions [r]: The engineering discipline of demolishing and clearing structures that are no longer needed, in both military and civilian contexts [e]


  • Explosively formed projectile [r]: A technique of using controlled explosives to direct a blast wave, or materials near it, into a desired shape [e]
  • Firearm [r]: Device, often designed to be used as a weapon, which projects either single or multiple projectiles at high velocity, using the energy of gases generated by a controlled explosion. [e]
  • Improvised explosive device [r]: A destructive device, not completely made from purpose-built military components, that is intended to cause destruction by means of an explosive charge and perhaps other components that increase damage [e]
  • TNT equivalent [r]: A unit of energy commonly used to quantify the energy released (or "yielded") in explosions. [e]

Characteristics of explosives and explosions

  • Combustion [r]: A sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat or both heat and light in the form of either a glow or flames. [e]
    • Deflagration [r]: Rapid, but not explosive (i.e., subsonic) self-sustaining combustion in explosive materials, especially low explosives such as black gunpowder and desensitized smokeless powder; the combustion wave propagates by thermal conduction; can produce explosion if confined but is more likely to produce controllable gases [e]
    • Detonation [r]: Extremely fast combustion in solids or fluids, which produces a supersonic shock wave with a detonation velocity; self-propagating through compression, heating and ignition of the explosive [e]
    • Detonation velocity [r]: The rate at which the detonation reaction propagates through an explosive material; in general, brisance is proportional to it [e]
  • Brisance [r]: The shattering power of an explosive; a measure of the rate at which it develops its maximum detonation velocity; usually expressed with respect to TNT (explosive), which has a brisance of 1.00 [e]
  • Explosive power [r]: The total power available from an explosive, measured with various tests of its ability to move mass rather than shatter it [e]
  • Overpressure [r]: The difference from normal air pressure caused by the shock wave generated by an explosion. [e]
  • Sympathetic detonation [r]: Explosion occurring when an "acceptor" explosive material detonates from the blast of a nearby "donor" explosion, with no interconnection between the donor and acceptor [e]
  • Blast (explosives) [r]: The process by which explosives convert to pressure in air or shock waves in more dense materials [e]
    • Blast injuries [r]: Injuries resulting when a person is struck by the pressure differentials of the shock wave of an explosion (primary); is struck by particles impelled with violent force from an explosion (secondary); is physically thrown about by the blast (tertiary); or is affected by fire, building collapse or other effects of the explosion on the victim's surroundings (quaternary) [e]
  • Cast density [r]: A property of explosives most often reported as a dimensionless number, but sometimes in grams per centimeter3; the same explosive chemical may be manufactured in different densities and crystal structures; complex detonation waves can be formed by mixing precisely machined shapes of dense and light explosives, of different detonation velocity, often intermixed with voids or inert material [e]
  • Spalling [r]: In general, the ejection of particles from a surface struck directly by a blast wave [e]
