Simulation CEL explosion in the depth of soil near the concrete piled-raft structure in Abaqus

In this tutorial, the Simulation CEL explosion in the depth of soil near the concrete pilled-raft structure in Abaqus  has been studied. The domain is modeled as three-dimensional Eulerian part. The concrete pilled-raft is modeled as three-dimensional solid part. The air, TNT, and soil are modeled as three-dimensional solid parts. You can see a figure of the assembled parts below

An explosion may be initiated by various methods. However, initiation of an explosive always goes through a stage in which a shock wave is an important feature. Jones–Wilkins–Lee or JWL material model is used to model the TNT behavior during the explosion. The Jones-Wilkins-Lee (or JWL) equation of state models the pressure generated by the release of chemical energy in an explosive. This model is implemented in a form referred to as a programmed burn, which means that the reaction and initiation of the explosive is not determined by shock in the material. Instead, the initiation time is determined by a geometric construction using the detonation wave speed and the distance of the material point from the detonation points. To model arri behavior, ideal gas model as an equation f state is selected. To model soil, the Mohr-Coulomb plasticity is considered. The concrete material model should be a specific model because of the damage and failure that happens during the explosion. Abaqus has some material models which they are available by using code. The dynamic explicit step is appropriate for this type of analysis. The general contact algorithm with contact property is selected. All boundary condition are assigned to the domain and concrete structure. To model Eulerian material, volume fraction method is considered. The mesh should be fine to get good results

After the simulation all results such ass stress, strain, damage, failure, wave propagation, wave velocity, soil compaction, and … are available. You can see some figures for the results below
