Fragmentation (weaponry)

Grooved body of a Second World War-era U.S. Mk 2 grenade. The grooves covering the exterior of the grenade are used to aid in the gripping of the grenade when throwing. A common misconception is that the grenade fragments along these grooves, which it does not.

Fragmentation is the process by which the casing of an artillery shell, bomb, grenade, etc. is shattered by the detonation of the explosive filler.

The correct technical terminology of these pieces is "fragmentation" (sometimes shortened to frag) – although "shards" or "splinters" can be used for non-preformed fragments. Preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and size and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated. The resulting high velocity fragments produced by either method are the main lethal mechanisms of these weapons, rather than the heat or overpressure caused by detonation, although offensive grenades are often constructed without a frag matrix.
