Overpressure (or blast overpressure) is the pressure caused by a shock wave over and above normal atmospheric pressure. The shock wave may be caused by sonic boom or by explosion , and the resulting overpressure receives particular attention when measuring the effects of nuclear weapons or thermobaric bombs .
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.

Overpressure is a pressure difference, relative to a normal pressure, in various circumstances: In engineering, the pressure difference over the wall thickness of a pressure vessel; In geology, geologic overpressure, the primary cause of oil gushers; In autoclave terminology, process pressure above standard given on a pressure/temperature table
The BAD is mainly caused by the high temperature and velocity armor and slug fragments being injected into the interior space and also overpressure (blast) caused by the impact. More modern SFF warhead versions, through the use of advanced initiation modes, can also produce rods (stretched slugs), multi-slugs and finned projectiles, and this in ...
Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
The Vietnamese Wikipedia (Vietnamese: Wikipedia tiếng Việt) is the Vietnamese-language edition of Wikipedia, a free, publicly editable, online encyclopedia supported by the Wikimedia Foundation. Like the rest of Wikipedia, its content is created and accessed using the MediaWiki wiki software.
Following the increasing of Internet usage in Vietnam, many online encyclopedias were published. The two largest online Vietnamese-language encyclopedias are Từ điển bách khoa toàn thư Việt Nam, a state encyclopedia, and Vietnamese Wikipedia, a project of the Wikimedia Foundation.
