Numerical Simulation of Explosion in a Confined Box-Shaped Structure

Article Preview

Abstract:

In order to study the propagation law of shock wave and blast load distribution when an interior explosion occur in a box structure, a numerical simulation of an interior explosion within a box-shaped structure is presented in this paper using LS-DYNA. Overpressure-time history curve of the blast load at the measured points is obtained by numerical simulation, and compared with the experimental results. Numerical simulation results and experimental results are in good agreement. The results show that the blast wave reflected and superimposed many times in the box-shaped structure. When TNT is located in the center of the box-shaped structure, the center and the corner of the wall suffered the maximum overpressure.
