Brisance (Shattering Power)

Definition

The localised shattering effect of a detonation shock wave, measured by the Trauzl lead block test or the sand-crush test. RDX and HMX have higher brisance than TNT despite lower detonation temperatures, because their higher detonation velocities produce sharper shock fronts.
