Numerical simulation of normal reflection shock wave of near-surface nuclear explosion
Abstract
The shock wave of near-surface nuclear explosions is of particular interest due to the wide range of destructive damage and destroy. In this study, the normal reflected shock wave of near-surface nuclear explosion is considered based on the similarity law of explosion. AUTODYN has also been utilized to simulate the reflected shock wave in the air. The numerical simulation indicates significant variations of peak overpressure of shock wave of explosive with different charge masses and HOBs from radial distances, and the result can be used to analysis the propagation and attenuation of reflected shock wave of nuclear explosion.
