Simulation CEL explosion inside the steel pipe embedded in the depth of soil in Abaqus

In this tutorial, the Simulation CEL explosion inside the steel pipe embedded in the depth of soil in Abaqus has been investigated. The pipe is modeled as a three-dimensional shell part. The TNT, soil, and air are modeled as a three-dimensional solid part. The Eulerian part is model as a three-dimensional Eulerian part. You can see a figure of the assembled parts at below

The steel material is used for the pipe as an elastic-plastic material with ductile and shear damage criterion to predict the failed zone after the detonation. The TNT behavior is modeled as an equation of state and that is JWL which can convert chemical energy released from the explosion process to the mechanical pressure. The air is modeled as an ideal gas with viscosity. To model soil behavior, Mohr-Columb plasticity is used. The dynamic explicit step is appropriate for this type of analysis. The general contact interaction with the contact property. The fixed boundary condition is assigned to the ends of the pipe and Eulerian boundaries are assigned to the Eulerian domain. The volume fraction method is used to calculate the volume of the TNT, soil, and sir. The mesh should be so fine to achieve good results

After the simulation, all results such as damage, stress, strain, failure, ….are obtainable. During the detonation, the TNT wave with its pressure causes huge damage to the pipe and penetrates it into soil and air. You can see some figures for the results below
