Simulation of a CEL large-scale bomb explosion(Nuclear detonation) near a building in Abaqus

In this tutorial, the Simulation of a CEL large-scale bomb explosion (Nuclear detonation) near a building in Abaqus has been investigated. A nuclear explosion releases vast amounts of energy in the form of blasts, heat, and radiation. An enormous Shockwave reaches speeds of many hundreds of kilometers an hour. The blast kills people close to ground zero and causes lung injuries, ear damage, and internal bleeding further away. In this tutorial, the bomb, air, soil, and concrete building are modeled as three-dimensional solid parts. You can see a figure of the assembled parts below

To model bomb behavior with its huge detonation pressure, 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 are 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, the Ideal gas equation of state is selected. To model soil, the More-Coulomb plasticity is selected. To model a concrete structure with a five-meter thickness, the Johnson-Holmquist is considered

The dynamic explicit step is appropriate for this type of analysis. The general contact and proper boundary conditions are assigned to all parts. The uniform material format is selected to define the bomb mass and its location near the ground and building. The mesh should be fine to obtain the correct results

After the simulation stress, strain, damage, massive blast wave propagation, detonation pressure, and other results are available. You can see some figures for the results below
