Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler.
The SD series was used primarily in two roles that were determined by the type of fuze and accessories fitted to the bomb. The first was as a fragmentation bomb with instantaneous fuze and when the bombs exploded above ground the case created large fragments which would kill enemy personnel and destroy unarmored vehicles.
The project was canceled in the late 1980s due to budgetary issues. [2] The prototype guided bomb in the canceled project was designated Type 7712. [3] A new laser-guided bomb project was initiated in 1992 after Chinese observation of the Gulf War. This project received more budgetary, human, and political resources.
Formation of an EFP warhead. USAF Research Laboratory.. An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance.
A bomb-making workshop discovered by Israeli Defense Forces in 2002, containing a large collection of nuts, bolts, and ball bearings to be used as shrapnel. Antipersonnel IEDs typically also contain fragmentation-generating objects such as nails, ball bearings or even small rocks to cause wounds at greater distances than blast pressure alone could.
An illustration of a fragmentation bomb from the 14th century Ming Dynasty text Huolongjing. The black dots represent iron pellets. Fragmentation is produced by the acceleration of shattered pieces of bomb casing and adjacent physical objects. The use of fragmentation in bombs dates to the 14th century, and appears in the Ming Dynasty text ...
The false claim that a 14-year-old student built an atomic bomb as a science project originates from a satirical website.
The fragmentation of the pipe itself creates potentially lethal shrapnel. Premature detonation is a hazard of attempting to construct any homemade bomb . The materials and methods used with pipe bombs often result in unintentional detonation, usually resulting in serious injury or death to the assembler.
