Abstract

Explosion problems can be examined in different environments. Due to the lesser-known nature of soil types and extent of the equations of state, explosion problems need careful analysis. Because of difficulties in laboratory explosion modeling, numerical models use to analyze this phenomenon Using the SPH methodology avoids the disadvantages of traditional numerical methods in treating large diformations in the extremely transient explosion process. Since explosion crater in the soil is an important problem and most of the studies are experimental, In this article it is tried to investigate the Craters diameter and height caused by the different amounts of explosives. The model is programmed with Fortran language and smooth particle hydrodynamics, SPH, the Craters, pressure caused by the explosion in the soil and the soil surface changes are also studied. To validate the model, the results of a laboratory study were used and it is shown that they are consistent with the numerical results of this study. Finally, Craters in a two layer soil is studied. This program can be used for modeling of Soil Explosion and Craters.
