Simulation SPH explosion inside the RC column with outer steel box cover in Abaqus

In this tutorial, the Simulation SPH explosion inside the RC column with outer steel box cover in Abaqus has been investigated. The concrete and TNT are modeled as three-dimensional solid parts. The steel box is modeled as a three-dimensional shell part. The steel bars and strips are modeled as three-dimensional wire parts. You can see figures of the assembled parts below

To model the steel behavior of the box, bars, and strips the elastic-plastic material model is used. To model the damage and failure during the detonation, the Johnson-Cook damage with evolution is selected. The JC criterion can predict failure under severe load like explosion. The JWL equation of state is used to model TNT behavior. 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 concrete behavior under severe pressure and dynamic load, Abaqus has some material models which they are appropriate for this simulation. These material models are available through the subroutine or input file modification. The dynamic explicit step and general contact algorithm are implanted. The perfect contact is assumed between steel box and concrete. The embedded region constrains is selected for the bar and strips. The fixed boundary condition is applied to the two ends of the column. The mesh should be fine to obtain good results

After the simulation, all results such as stress, strain, damage, failure, and … are obtainable. You can see some figures for the results below
