Crater effects of shallow burial explosions in soil based on SPH-FEM analysis

This study analyzed the effects and influencing factors of shallowly-buried explosions in soil based on design implementation static explosion experiments numerical simulations. Based test data, a analysis model SPH-FEM was established process pit parameters shallowly buried were analyzed. The results calculations comparisons verified effectiveness method simulating soil. Furthermore, similarities differences between ALE methods simulation same assessed. relationships blasting radius explosive depth, explosives weight volume empirical curve formula depth crater with 9.35 kg TNT obtained by mathematical fitting. showed that more refined computationally efficient than to simulate shallow burial formula, which expressed relationship radius, effectively predicted explosion. With increasing increased peak value then decreased rapidly.
