A CALCULATION METHOD OF OVERPRESSURE ON NONIDEAL EXPLOSIVES EXPLODING IN AIR

摘要

A new evaluation method for overpressure calculation is established and validated with experimental data. The blast heat is used for the overpressure calculation of nonideal aluminum-contained RDX-based explosives. The relationships of overpressure with the square of the detonation velocity and explosion heat are established, and the contributions to overpressure are reflected by the Salovskii empirical equation. This is essentially in accordance with the expressions obtained from the energy conservation law.
