The duration of the blast wave depends on the type of explosive material and the distance from the point of detonation. The blast wave progresses from the source of explosion as a sphere of compressed and rapidly expanding gases, which displaces an equal volume of air at a very high velocity. The velocity of the blast wave in air may be ...
Many modern Western tanks (for instance, the M1 Abrams, Leopard 2, and Leclerc) feature ammunition compartments designed to fail safely under fire, reducing damage to the level of a firepower kill. In such designs, when the tank is damaged, blowout panels open to channel ignited propellants and explosives away from the crew cabin. While the M1 ...
The human body can survive relatively high blast overpressure without experiencing barotrauma. A 5 psi blast overpressure will rupture eardrums in about 1% of subjects, and a 45 psi overpressure will cause eardrum rupture in about 99% of all subjects. The threshold for lung damage occurs at about 15 psi blast overpressure.
New images by European Space Imaging reveal full extent of the damage caused by blast at Al Ahli hospital in Gaza
The risk of lung trauma is very high, as is the danger from any unsecured objects that can become projectiles because of the explosive force, which may be likened to a bomb detonation. Immediately after an explosive decompression, a heavy fog may fill the aircraft cabin as the air cools, raising the relative humidity and causing sudden ...

US scientists with a full-scale cut-away model of the W48 155 millimeter nuclear artillery shell, a very small tactical nuclear weapon with an explosive yield equivalent to 72 tons of TNT (0. ...
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the ...
For example, a tank's main gun can fire armor-piercing ammunition in the anti-tank role, high-explosive ammunition in the anti-structure role and fragmentation shells in the anti-personnel role. There are also more exotic classes of weapons, such as neutron bombs , chemicals , and biological weapons , which are only designed to attack people.
