Quantification of four characteristics of the incident shock wave.

The peak overpressure (A), impulse (B), rise time (C) and duration (D) for three nominal BOPs used in the experimental design are presented. The evolution of the peak overpressure and impulse values is expressed as a function of sensor distance from the membrane mounting port. The bar plots were used to illustrate the evolution of the rise time and duration as a function of sensor location and BOP. Asterisk indicates the statistical significance exists between respective groups shown in both plots.
