Risk analysis about explosions in train carriages
by M. Larcher
International Journal of Materials Engineering Innovation (IJMATEI), Vol. 2, No. 2, 2011

Abstract: Land mass transport systems have an open architecture and are therefore vulnerable to terrorist attack. The risk of injuries and fatalities in case of an explosion inside trains can be minimised by optimising these structures. Fluid-dynamic calculations are performed to investigate the risk inside a train carriage. The structural part of the train is built up from aluminium. Special failure models are used for laminated glass. Two structures of the train body are investigated. A honeycomb structure results in small displacements and limited failure. The risk inside such a train is much higher than in a train built from a frame structure, where a thin sheet of aluminium is welded on. The influence of the glazing and of internals on the risk inside a train is also discussed in the paper.
