Open publisher page 3 citations

Abstract

We simulated the propagation of the shock wave produced by TNT explosions in infinite air with LS-DYNA,and got the overpressure and positive impulse which agree with the related experimental results.We also discussed the influence of the mesh sizes and nonreflecting boundary conditions on the calculation results,and simulated the shock wave produced by the explosions with 1kg,1tand 1kt TNT explosives,finding a result in accordance with the similarity law of explosion in air.
