Simulation SPH explosion near RC slab by using CDP model couple with strain rate in Abaqus

In this tutorial, the Simulation SPH explosion near RC slab by using CDP model couple with strain rate in Abaqus  has been investigated. The RC slab is modeled as a three-dimensional solid part. The steel bars are modeled as three-dimensional wire part. The TNT is modeled as a three-dimensional solid sphere. You can see a figure of the assembled parts below

The damage-plastic constitutive behavior of concrete is represented by the Concrete Damaged Plasticity (CDP) model. Arguably the CDP model is one of the most popular concrete damage-plasticity models in the literature and engineering practices.It is one of most promising concrete constitutive models used for simulation of concrete damage and failure. The tensile and compression data depend on strain to consider the rapid deformation is used. To model steel bars behavior, the elastic-plastic material depend on strain rate is selected. To model TNT , the JWL equation of state has been used. The Jones-Wilkens-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. The dynamic explicit step is appropriate for this type of analysis. The embedded region constraint is consider for the steel bars inside the the concrete slab. The general contact capability is selected to consider all contacts in the contact domain. The fixed boundary condition is assigned to two sides of the RC slab. The mesh should be fine to obtain correct results and observe the tensile crack propagation

After the simulation, all results such as stress, strain, tensile and compressive damage, displacement, and … are available. You can some figures for the results below
