WebIn this study, the confined explosion characteristics of ethyl acetate were investigated in a constant volume explosion vessel using the initial pressure of 1? WebApr 10, 2024 · A concussive wave is a blast of energy given off by an exploding object. Further, the explosion compresses the air immediately surrounding the site of detonation. As a result, the compressed air scatters in all directions away from the source - growing weaker the further, the wave travels.

Blast wave - Wikipedia

WebA longitudinal wave consists of a repeating pattern of compressions and rarefactions. Thus, the wavelength is commonly measured as the distance from one compression to the next adjacent compression or the distance from one rarefaction to the next adjacent rarefaction.

"WebIn the simplest approximation, an explosion is a shockwave moving out from some locus. The shockwave may be a compression front in a ambient medium, or may be a wave of gas propagating from the explosive into a vacuum. So that's the first thing you need to tell us: in air, water, vacuum, or what? " - Explosion compression wave

Explosion compression wave

WebAn explosively pumped flux compression generator ( EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive . An EPFCG only ever generates a single pulse as the device is physically destroyed during operation.

WebA 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. WebThe main sources of inelastic behavior of short fiber composites are identified: (a) damage related reduction of thermo-mechanical properties; (b) nonlinear viscoplastic strains developing with time at high stresses; (c) nonlinear viscoelasticity. These phenomena are included in the material model.

WebThe convergent shock wave of an implosion can compress solid uranium or plutonium by a factor of 2 to 3. The compression occurs very rapidly, typically providing insertion times in the range to 1 to 4 microseconds. The period of maximum compression lasts less than a … WebThis rapidly expanding gas, called a pressure wave, is the key to any explosive's destructive power. If the pressure wave is fast enough to break the sound barrier, it generates a powerful shock wave. A land explosion can burn skin, tear apart limbs and propel objects and shrapnel through the air.
