peak overpressure

The maximum value of overpressure at a given location which is generally experienced at the instant the shock (or blast) wave reaches that location.

Equivalent overpressure time-histories are given by (8) such that the peak overpressure ([P.sub.o]) is equal to the recorded peak overpressure, and equivalent positive phase duration [t.sub.eq] is given by the following equation:
VCEs are very dangerous because they tend to have a high peak overpressure for a relatively long duration and hence a very high impulse.
The peak overpressures recorded by those pressure transducers [24] and the numerical results obtained from the present work were summarized in Figure 3.
Beyer [39] visualized the path of the incident wave diffracting over the blast wall as shown in Figure 9 and reported attenuated positive peak overpressure behind the wall.
Multiple studies have confirmed that microcontusion and microhemorrhaging of the BBB occurs with a lower threshold of 200 kPa peak overpressure in direct cranial and lateral blast exposure models [49, 69].
Peak Overpressure. The results for the peak overpressure were obtained by using LabView program.

Normalized peak overpressure ratio could be correlated with inlet diffusion area ratio (AR); this correlation is illustrated in the figure shown on this page.
Samples were exposed to an average of 18.37 psi (127 kPa) peak overpressure, which corresponds to mild severity injury in preclinical rodent models [14, 15].
