What does brisance?
Definition of brisance : the shattering or crushing effect of an explosive measurable by the crushing of sand or the compression of a metal cylinder and dependent upon the rate of detonation and other factors.
What is the highest velocity explosive?
Octanitrocubane
Octanitrocubane has a detonation velocity of 10,100 m/s, making it the fastest known explosive.
How is Brisance measured?
A practical method of measuring brisance is the sand crush test, in which a measured sample of explosive is detonated in sand (of 30 mesh grain size), and the shattering effect on the grains of sand is evaluated by sieving after for change in the sand grain size. The sand test is also used to determine TNT equivalency.
What is PETN made of?
Carbon, hydrogen, nitrogen, and oxygen are the only elements in PETN (Figure 4). Under normal laboratory conditions, there are no labile atoms, and therefore the stable isotope signature is preserved despite exposure to air, light, moisture, and dissolving organic solvents such as acetone and acetonitrile (J.
What are the three types of explosion?
There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.
How are explosives made?
Chemical composition A chemical explosive may consist of either a chemically pure compound, such as nitroglycerin, or a mixture of a fuel and an oxidizer, such as black powder or grain dust and air.
What is detonation material?
Detonation—Is a propagating chemical reaction of a substance in which the reaction front advances into the unreacted substance at greater than sonic velocity in the unreacted material.
What are the 2 types of explosions?
There are two major categories, high explosives and low explosives.
What is the root word of brisant?
(brĭ-zäns′, -zäNs′) n. The shattering effect of the sudden release of energy in an explosion. [French, from brisant, present participle of briser, to break, from Old French brisier, from Vulgar Latin *brisiāre, perhaps of Celtic origin.] bri·sant′ (-zänt′, -zäNt′) adj.
What is the charge density of a brisant explosive?
Two charges should be used: a cratering charge, and a small charge of a brisant explosive. It is highly brisant with a VoD of 7300 ms-1 at a charge density of approximately 1.5 g cm-3. Borrowed from French brisant . m.
What is the most brisant type of explosive?
Brisance. One of the most brisant of the conventional explosives is cyclotrimethylene trinitramine (also known as RDX or Hexogen). RDX is the explosive agent in the plastic explosive commonly known as C-4, constituting 91% RDX by mass.
How brisant is the propellant in a rocket?
The propellant tank showed evidence of high internal pressure but no brisant detonation. Two charges should be used: a cratering charge, and a small charge of a brisant explosive. It is highly brisant with a VoD of 7300 ms-1 at a charge density of approximately 1.5 g cm-3.
