  Explosive material - Wikipedia, the free encyclopedia
Explosives are classified as low or high explosives according to their rates of decomposition.
The term "detonation" is used to describe an explosive phenomenon whereby the decomposition is propagated by the explosive shockwave penetrating the explosive material.
Explosive force is released at 90 degree angles from the surface of an explosive.

 Kids.net.au - Encyclopedia Explosive material -
There are many other varieties of more exotic explosive material, such as nuclear explosives and antimatter, and other methods of producing explosions, such as abrupt heating with a high-intensity laser or electrical arc[?].
Explosives are classified by their sensitivity, which is the amount of energy to initiate the reaction.
The procedure for calculating oxygen balance in terms of 100 grams of the explosive material is to determine the number of gram atoms of oxygen that are excess or deficient for 100 grams of a compound.

 Plastic explosive - Wikipedia, the free encyclopedia
Plastic explosives are especially suited for explosive demolition as they can be easily formed into the best shapes for cutting structural members, and have a high enough velocity of detonation and density for metal cutting work.
One of the earliest plastic explosives was Nobel 808, developed well before World War II and used extensively by British SOE forces during that war.
The samples of explosive brought to the USA by the Tizard Mission had been packaged by SOE ready for dropping to the French Resistance and were labelled in French, as Explosif Plastique.

 explosive. The Columbia Encyclopedia, Sixth Edition. 2001-05
Low (or deflagrating) explosives are used primarily for propelling; they are mixtures of readily combustible substances (e.g., gunpowder) that when set off (by ignition) undergo rapid combustion.
High (or detonating) explosives (e.g., TNT) are used mainly for shattering; they are unstable molecules that can undergo explosive decomposition without any external source of oxygen and in which the chemical reaction produces rapid shock waves.
Nondetonating explosives, e.g., gunpowder and the smokeless powders, have found extensive use as propellants for bullets and artillery shells.

 Explosive material   (Site not responding. Last check: 2007-10-22)
High Explosives explode in supersonic reactions and without confinement, are compounds, are initiated by shock or heat and have high brisance (the shattering effect of an explosion).
Some secondary explosives are insensitive enough that they can be lit with a match -- or a torch -- and will simply burn like wood; a detonation wave is never formed.
There is no sharp line of demarcation between low and high explosives, due to the difficulties inhehent in precisely observing and measuring rapid decomposition.

 Military Explosives Chapter 12
Explosives are classified as low or high explosives accord-ing to their rates of decomposition.
All of the standard military explosives may be considered to be of a high order of stability at temperatures of -10o to +35oC, but each has a high temperature at which the rate of decom-position becomes rapidly accelerated and stability is re-duced.
The sensitivity, strength, and brisance of an explosive are all somewhat de-pendent upon oxygen balance and tend to approach their maxi-mums as oxygen balance approaches zero.

 Fuel/Air Explosive (FAE)
For gasoline vapor, the explosive range is from 1.3 to 6.0% vapor to air, and for methane this range is 5 to 15%.
Conventional high explosive munitions also produce fragments from the munition case, as well as fragments from material in the target area that is broken loose by the high blast overpressures.
Based on the known properties of flammable substances and explosives, it is possible to use conservative assumptions and calculate the maximum distance at which an overpressure or heat effect of concern can be detected.

 Explosive Exercise
Before discussing explosive exercise in detail it is necessary to define terms and present a theoretical background for the discussion.
Explosive exercise can be defined as a movement in which maximum or near maximum rates of force development are attained.
Evidence of this relationship can be observed in Figure 2 Note in that in tracing A the initial rate of activation and force development is higher than in tracing B. Thus, the rate of force development is largely a function of the nervous system's ability to activate muscle.
