Fragmentation is the process by which the casing of an artillery shell, bomb, grenade, etc is shattered by the detonating high explosive filling. Artillery (from French artillerie) is a military Combat Arm which employs any apparātus machine A shell is a payload-carrying Projectile, which as opposed to shot, contains an explosive or other filling though modern usage includes large solid projectiles A bomb is any of a range of devices that typically rely on the Exothermic Chemical reaction of an Explosive material to produce an extremely Detonation is a process of Supersonic Combustion in which a Shock wave is propagated forward due to energy release in a reaction zone behind it An explosive material is a material that either is chemically or otherwise Energetically unstable or produces a sudden expansion of the material usually accompanied The correct technical terminology for these casing pieces is fragments, shortened to frags, although shards or splinters can be used for non-preformed fragments. The fragments, as mentioned previously, can also be preformed and of various shapes (spheres, cubes, etc) and sizes. Preformed fragments are normally held rigidly within some form of matrix, or body until the HE filling is detonated. The resulting high velocity fragments produced by either method are the main lethality mechanisms of these weapons. The word shrapnel is often used to describe these fragments, the word shrapnel originally referred to a specific type of shell, the shrapnel shell, which doesn't rely on a high explosive to shatter the casing. Shrapnel is the term originally applied to an anti-personnel artillery shell which carried a large number of individual bullets to the target and then ejected them forwards relying Shrapnel is the term originally applied to an anti-personnel artillery shell which carried a large number of individual bullets to the target and then ejected them forwards relying Shrapnel is the term originally applied to an anti-personnel artillery shell which carried a large number of individual bullets to the target and then ejected them forwards relying A World War I era shrapnel shell uses a small (black) powder charge in the base of the shell to expel the lead or iron shot at a relatively low velocity, 200 m/s (700 ft/s). World War I (abbreviated WWI; also known as the First World War, the Great War, and the War to End All Gunpowder is a an explosive mixture of Sulfur, Charcoal and Potassium nitrate (also known as saltpetre/saltpeter that burns rapidly producing volumes Characteristics Lead has a dull luster and is a dense, Ductile, very soft highly Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 The expulsion, at a predetermined time and height above the target area, is controlled by a time fuse. In an Explosive, Pyrotechnic device or military Munition, a fuse (or fuze) is the part of the device that initiates function Due the low velocity of the shot, unlike the fragments produced by a detonating HE munition, it is only really effective against human targets, not material or armor.
