Numerical simulation of explosion scenarios in a real metro station

Major efforts have been devoted in the last years to enhance transport security by detecting the vulnerabilities in the current public transportation structures, in particular rail and metro stations, and to propose measures to improve their resilience. The present work shows a complete study of an explosion event in a real metro station, by numerical simulations. In the simulations, fluid structure interaction techniques in combination with blast loading conditions are taken into account. Moreover, large deformation up to fragmentation of the structure and its interaction with the finite element mesh is handled. A special methodology is used in order to separate the fluid from the structural mesh and to make them non-conforming. EUROPLEXUS fast transient dynamic finite element code has been selected for the present investigation. Concerning the outputs emphasis has been given to the determination of fatal and non-fatal injuries risk.
