NUMERICAL SIMULATION AND DAMAGE EFFECTS OF THE NEAR-GROUND CLOUD DETONATION OVERPRESSURE FIELD

The space-time distribution of FAE detonation overpressure field is simulated by means of Object-MMIC, a dynamic program, in this paper. The changing pattern of damage radius and area of shock wave with effectivity are analyzed. It is found that the overpressure field can be divided into three subareas, namely, the direct action area of cloud detonation, the united action area of the detonation outcome and the shock wave, the shock wave action area. The damage area of cloud detonation shock wave increases linearly with the total energy of cloud detonation.
