Resumen:
In case of terrorist attacks or other intentional actions using explosives, the information that
can be obtained from the crater generated by the blast waves is extremely important. For example, the
focus of the explosion and the mass of the explosive used in the attack can be deduced examining the
location and dimensions of the crater. However, studies about craters produced by explosions on or
above ground level, which would be the case when the explosive charge is situated in a vehicle, are
rarely found in the open technical literature.
A numerical study related to crater produced by small to medium explosive loads located on the soil
surface was presented in previous papers. In this paper, a study about the craters created by exploding
charges ranging from 120 kg to 1900 kg of TNT. The charge consists of different ordnances stacked in
different configurations.
The crater diameters and depths for all explosive loads tested at the Touwsrivier Training Area (South
Africa) were obtained. Moreover, the effect of the boundary conditions is analyzed and discussed.
The arrangement of the explosive load has significantly importance in the final dimensions of the
crater. The final crater dimension can be larger, similar or smaller than those obtained with an
equivalent spherical charge
