The strength, or potential, of an explosive is the total work that can be performed by the gas resulting from its explosion, when expanded adiabatically from its original volume, until its pressure is reduced to atmospheric pressure and its temperature to 15°C. The potential is therefore the total quantity of heat given off at constant volume ...
The Trauzl lead block test, also called the Trauzl test, or just Trauzl, is a test used to measure the strength of explosive materials. It was developed by Isidor Trauzl in 1885. Trauzl lead block before and after a test (1 – sand | 2 – Explosive and detonator | 3 – lead)
The introduction of water into an explosive is highly undesirable since it reduces the sensitivity, strength, and velocity of detonation of the explosive. Hygroscopicity is a measure of a material's moisture-absorbing tendencies.
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
As a general rule, PETN is considered to be either a relatively insensitive primary explosive, or one of the most sensitive secondary explosives. PETN may be detonated by striking with a hammer on a hard steel surface (a very dangerous thing to do), and is generally considered the least sensitive explosive with which this may be done.
For example, high-explosive 65% Extra dynamite has a weight strength of 65% ammonium nitrate and 35% "dope" (the absorbent medium mixed with the stabilizers and additives). Its "cartridge strength" would be its weight in pounds times its strength in relation to an equal amount of ANFO (the civilian baseline standard) or TNT (the military ...
Strength Training for Explosive Power The definition of power is strength times speed, Comana says. So, the goal of explosive power training is to move a weight as fast as you can, Rottenberg says.
RDX is the explosive agent in the plastic explosive commonly known as C-4, constituting 91% RDX by mass. [5] Fragmentation occurs by the action of the transmitted shock wave, the strength of which depends on the detonation pressure of the explosive. Generally, the higher this pressure, the finer the fragments generated.
