Detonation velocity, also known as velocity of detonation (VoD) or explosive velocity, is the velocity at which the shock wave front travels through a detonated explosive.

General

Explosive velocity is increased with smaller particle size (i.e. increased spatial density), increased charge diameter, and increased confinement (i.e. higher pressure). Detonation velocities depend on the explosive material's phase: in gases it ranges from 1800 m/s to 3000 m/s, while in solid explosives between 4000 m/s to 10300 m/s.

Relative effectiveness factor (R.E. factor) is a measurement of an explosive's power. It measures the detonating velocity relative to that of TNT, which has an R.E. factor of 1.00.

Explosive velocities are always faster than the local speed of sound in the material.[1][2]
