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.
A mine shell (from German: Minengeschoss, "mine shot") or high-explosive, high-capacity (HEHC) [a] in British military nomenclature, [1] [2] [3] is a military explosive shell type characterized by thin (usually steel) shell walls and a correspondingly high quantity of explosives, much higher than the traditional high-explosive shell type per caliber, meaning that mine shells trade ...
In warfare, high-explosive incendiary (HEI) is a type of ammunition specially designed to impart energy and therefore damage to its target in one or both of two ways: via a high-explosive charge and/or via its incendiary (fire-causing) effects. Each round has both capabilities.
When allowed to impact, the TNT filling would detonate, becoming a high-explosive shell with a very large amount of low-velocity fragmentation and a milder blast. Due to its complexity it was dropped in favour of a simple high-explosive shell. During World War I the UK also used shrapnel pattern shells to carry "pots" instead of "bullets".
It is filled with fragments and powerful explosive compositions based on TNT/RDX. The design of this aircraft bomb provides for better fragments distribution in the fragments flight area and high density of the fragmentation zone within the lethal range as compared to general-purpose munitions. [3]
The M795 is a 155 mm high-fragmentation, steel (HF1)-body projectile, filled with 10.8 kilograms (23.8 lb) of TNT.It weighs approximately 47 kilograms (103 lb). The high-fragmentation steel body is encircled by a gilding metal rotating band, making it compatible with 3W through 8S (M3A1 through M203A1) zone propelling charges across all current 155 mm howitzers.
Post-World War II German DM41 fragmentation hand grenade filled with Composition B. This example has been dissected to reveal the steel fragmentation sleeve and yellow explosive charge. Composition B (Comp B), also known as Hexotol and Hexolite (among others), is a high explosive consisting of castable mixtures of RDX and TNT.
An important consideration in the analysis of the hazards associated with an explosion is the effect of any fragments produced. Although fragmentation most commonly occurs in high explosives events, fragmentation may occur in any incident involving ammunition and explosives (A&E).
