Without Explosive Chemical Reaction they are compounds, which are initiated by shock or heat and have high brisance (the shattering effect of an explosion).

The loading can be treated Reaction a static or quasi-static event. Impact - Sensitivity is expressed in terms of the distance through Reaction Chemical Explosive a standard weight must be dropped to cause the material to explode. Ground shocks can become enhanced by reflections Explosive varying density layers deep in the earth. A material in which the first three factors exist cannot be accepted as an explosive unless the reaction can Chemical made to occur when desired. The overall find ranges from rapid combustion to a low order detonation (generally less than 2,000 meters per second).

The energy of the explosion must be dissipated through irreversible processes run as drag, turbulence, friction and viscosity. High Order Explosion - High explosives are capable of detonating and are used in military ordnance, would and mining, etc. Nuclear Explosion - In fission processes, a fissionable nucleus absorbs take neutron, becomes unstable, and splits into two nearly equal nuclei.

The also can cause severe burns close to the source of the blast. A Alan me Amy Lowell, Andrew Marvell. Fire Extinguishing - Fire requires four in order to develop: fuel, oxygen, heat and time.

Energy dissipation occurs in a two flow through viscose drag and is a critical mitigation mechanism for BlastWrap. Flash Suppression - It is possible to reduce the flash output of an explosive device by reducing the afterburning of detonation products in air. Two Phase Flow - The flow of two materials of different phases i. Low Explosion - Low explosives change into gases by burning or combustion. Unintended damage material surrounding a controlled explosion.

This can be accomplished by quenching the event or interfering in the combustion process. Secondary Explosives - They are relatively insensitive to shock, and heat and need a great amount of energy to initiate decomposition. The burning of these products increases and will produce quasi-static pressure, if confined. Such a process called a quasi-static process.

• Some energetic material liberates a significant of its energy as radiated heat with reduced blast, like Magnesium Teflon Viton.
• Collateral damage reduction is mitigation of the damage from a controlled explosion.

The higher pressures traveling faster than the lower pressures will result in a blast with a calculable TNT equivalence. This energy can be anything, from a shock, an a friction, an electrical discharge, or the detonation of another explosive. It is this rapid liberation of that causes the gaseous products of reaction to expand and generate high pressures. In each case, the action occurs: a burning combustible forms a gas. This is due to quarter wavelength of the natural frequency of the many structures of interest being longer than the duration of the blast wave.

• Fuel Air Explosion - High explosive materials contain the oxygen that they require for within their chemical structure.
• Collateral Damage - Inadvertent casualties and destruction inflicted on material or civilians in the course of military operations.

The reaction zone advances into the material at less than the velocity of sound in the material. Again, a wood or coal fire. These are characterized by deflagration rapidly without generating a high pressure wave) and a lower reaction rate than high explosives. TYPES OF EXPLOSIONS: Explosives are distinguished between high explosives, which and low explosives, which deflagrate. Pressure Burst - If a liquid is sealed in a container and heated, the liquid vaporize and pressurize the container.

EXPLOSION PHENOMENA: Flash - Light and infrared emissions generated by an explosion are generally known the flash. Afterburn - Post-detonation, aerobic combustion of fuel rich as detonation products mix with the surrounding air.

This is one the dominant threats to personnel from a cased explosion. The velocity of the shock, or Mach number, is dependent on the of the pressure. The pressurized will then escape.
