Simulation under ground explosion inside two concrete tunnels in Abaqus by using CEL approach

An explosion on the ground surface can cause significant damage to a tunnel located at a shallow depth below groundA comprehensive approach to simulate the effects of an explosion occurring inside a buried infrastructure tunnel on the soil surface and on nearby tunnels is presented. The approach considers all the stages of the complex process: detonation of the internal explosive charge; the shock wave propagation through the air in the tunnel. To model all parts three dimensional space has been used. Concrete tunnel is modeled with JC material, air as ideal gas,TNT as JWL and soil with Coulomb-Mohr plasticity. Dynamic explicit procedure is appropriate for this type of analysis and for modeling TNT behavior Volume Fraction method has been implanted. You can see some figures of this simulation at below
