Simulation Eulerian Explosion over Concrete Wall in Abaqus

In this tutorial simulation CEL( Couple EulerianLagrangian) explosion over the concrete wall has been investigated. .TNT and Air are modeled as a Eulerian parts and Concrete as a Lagrangian part. To model TNT behavior JWL equation of state and to model air behavior Us-Up equation has been used. The JWL equation has this capability to convert chemical energy released from the explosion to mechanical pressure.

Dynamic explicit is appropriate for this type of analysis.Genaral contact algorithm is used as contact. To model Eulerian procedure there are two way, the first way is volume fraction and the second way is uniform material assignment. In this simulation the second way is used. The mesh quality for Eulerian part are so suitable to get the better result. You can see some figures of this simulation at below
