Abstract : In this study, numerical simulations were conducted using SPH (Smoothed Particle Hydrodynamics) with Hyper Works-RADIOSS (®Altair) software with the aim of positively reducing the evacuation radius set up when unexploded ordnance is disposed. We constructed an analytical model that takes into account the actual bomb geometries and finely discretized the SPH pitch compared to simulations conducted in previous studies to observe the fragments behavior more detailed. Furthermore, we observed changes in the fragment‟s behavior due to differences in soil types. the computational results have been observed that the fragments behavior is significantly dependent the characteristic of soil and the amounts of explosive.
