Keywords: stiffened panel, dynamic loading, buckling

This paper studies the structural behaviour by numerical simulation of ortothropically stiffened aircraft panels subjected to dynamic buckling loading of different duration pulses. Particular attention is paid to buckling onset, failure load and possible changes in the failure mode.
