Throughout the years, underground tunnels have offered a quick and cost effective alternative to address transportation requirements in many countries. Terrorist attacks, such as the bombing of the Moscow Metro in 2004, London Subway in 2005, and Belarus in 2011, highlight that these structures should be carefully designed to withstand such events. The main method terrorists used to implement these attacks is using a vehicle bomb because of its enormous charge power, high success rate and serious demolition. In this video Eulerian explosion inside the concrete tunnel in the depth of soil was done in Abaqus software. Three dimensional part was used for member as tunnel,soil,air and TNT. To model TNT behavior JWL equation,for soil Mohr-Coulomb plasticity, for air EOS as ideal gas and for concrete tunnel CDP model has been used. Dynamic explicit step was performed for this type of analysis. Generally explosion has two way for modeling, first uniform material and the second is volume fraction method. In this study volume fraction method was used. You can see some figures of this simulation at below
