Overpressure
Pressure due to a shockwave / From Wikipedia, the free encyclopedia
This article is about shock waves in the atmosphere. For other uses, see Overpressure (disambiguation).
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.
