A Computational Simulation for Explosive Ordnance Disposal

Abstract:

In order to clarify the characteristic behavior such as shockwave propagation, dispersion of sand and the crater depth due to explosive ordnance disposal, the finite element models of soil, surrounding air and explosive have been constructed based on HyperWorks-RADIOSS (®Altair) software. By conducting a series of numerical simulations, it has been observed the effect of explosion on the crater depth and diameter, overpressure exerted on sand and the surrounding air. These results based on the computational mechanics are useful data for setting the evacuation area and its distance associated with an explosive ordnance disposal.
