reflected pressure

[ri′flek·təd ′presh·ər]
(physics)
The pressure from an explosion (especially an airburst bomb), which is reflected from a solid object or surface, rather than dissipated in the air.

The charge detonates in air, and the reflected pressure history at the projective point of the detonation center on the left floor is shown in Figure 8.
The peak reflected pressure on the target building at the T-junction was found 300% greater than empirically (free field) measured pressure.
Systolic BP is a result of the interaction between ejected stroke volume and the dampening function of large arteries and propagative and reflected pressure waves.
When the incident pressure wave impinges on a structure that is not parallel to the direction of the wave's travel, it is reflected and reinforced, producing what is known as reflected pressure. The reflected pressure is always greater than the incident pressure at the same distance from the explosion.
The CONWEP algorithms do account for incidence angle by combining the reflected pressure (normal-incidence) value and the incident pressure (side-on incidence) value, and the formula from TM5-1300 [29] is used in the method.
Augmentation index (AI), a marker of the interaction of incident pressure wave and reflected pressure wave, was significantly and inversely related to heart rate due to an alteration in the relative timing of the reflected pressure wave [19].
The envoy said that the EU's ties with Hezbollah were strategic, and dismissed Hezbollah's criticism that the decision reflected pressure from external actors.
Moreover, the reflected pressure waves tend to increase the load to the heart and play a major role in determining the wrist-pulse waveform patterns [5-7].
There were two results of analysis: peak reflected pressure at the plate surface, and incident overpressure in the air at the same distance from the inlet.
A typical explosive loading generated by a distant explosion is characterised by its peak reflected pressure [P.sub.r,max] and positive phase duration [t.sub.+], whereas the negative phase is usually ignored in the explosive damage assessment.
The downgrades reflected pressure on the bank's financial strength as a result of heavy investment losses on proprietary investments in September and October 2008 and also because of the deteriorating operating environment for alternative investment providers.
As shown, in Figure 8, the magnitude of reflected pressure increases markedly with decreasing frequency.
