Blast wave - Wikipedia
In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative gauge pressure, which sucks items back in towards the center. The blast wave is harmful especially to objects very close to the ...

Blast, thermal radiation, and prompt ionizing radiation cause significant destruction within seconds or minutes of a nuclear detonation. The delayed effects, such as radioactive fallout and other possible environmental effects, inflict damage over an extended period ranging from hours to …
Explosive detonations create an incident blast wave, characterized by an almost instantaneous rise from atmospheric pressure to a peak overpressure. As the shock front expands pressure decays back to ambient pressure, a negative pressure phase occurs that is usually longer in duration than the positive phase as shown in Figure 4-1.

The Blast Wave. A fraction of a second after a nuclear explosion, the heat from the fireball causes a high-pressure wave to develop and move outward producing the blast effect. The front of the blast wave, i.e., the shock front, travels rapidly away from the fireball, a moving wall of highly compressed air.
Blast Wave - an overview | ScienceDirect Topics
A blast wave is generated from an explosion by sudden release of a large amount of energy in a very small volume (see Fig. 4). A blast wave usually consists of a shock wave and a blast wind [30]. Nonlinear physics that explains shock waves is also used to describe blast waves [140,141].

2016年3月3日 · 7.1 Wave Type. Wave motion can be broadly defined into three classes, compression, tension and shear. Compressive waves are associated with positive stresses and pressures, tensile waves with negative stresses and pressures, while shear waves produce motion lateral to their direction of propagation.

This book examines blast waves—their methods of generation, their propagation in several dimensions through the real atmosphere and layered gases, and their interactions with simple structures—thereby providing a broad overview of the field.

2012年4月4日 · A blast wave refers to the wave of pressure and energy that radiates outward from an explosion, which can be either ideal or nonideal depending on the conditions such as shock reflections, multiple-blast sources, and nonuniform shock speeds.
Blast Wave - an overview | ScienceDirect Topics
It is an area of compressed air expanding supersonically outward from an explosive core, which has a leading shock at the front of the compressed gases. As the wave propagates away from the explosive core, the pressure of the compressed air at the blast wave front reduces.
