| Abstract: | Peak pressures of underwater explosion wave by a spherical charge of composition B-3 are measured by using manganin gauge, PVDF gauge and tourmaline gauge over scaled distance of 1≤R/R0≤400, and the attenuation of the peak pressure is obtained. The explosion energy of composition B-3 is worked out from pressure profiles obtained by tourmaline gauges and the data of the first pulsation period of gas bubble. This energy is similar to the value from the explosion heat test. This result proves the possibility of assessment of explosive energy by using underwater explosion test. |
