Blast actions in aircrafts: An integrated methodology for designing protection devices

We introduce a numerical approach for evaluating the behaviour of aircraft fuselages subjected to internal explosions. At variance with available approaches, we consider fluid-structure interactions through a novel integrated methodology able to take into account both stress at cruise altitude and blast fast-dynamics in interaction with pressurization not considered as a static load. The precision of the proposed numerical procedure allows us to foresee a nonstandard composite protective device.
