Popis:	Brisance effects were measured by the crushing of a copper cone by the stress wave set up by an explosive. The crushing effect was mitigated by the presence of layers of particulate material. The mitigation was principally achieved by the energy used in consolidating the particulate material. This was a function of the particle size of the sand used and was greatest for a fine-grained sand. For military explosives relative brisance effects measured by cone crushing were similar to those calculated by formulas derived from analysis of the chemistry of the explosive, but results for the lower detonation velocity nitromethane explosive gave values somewhat higher than those derived from chemistry-based formulas.
