Interaction of multiple axial pre-cracks in a pressurized fuselage was investigated using a small scale model of an idealized fuselage. Stain between multiple cracks under rapidly cracks propagation was measured. The recorded crack velocities justified the use of a successive finite element analysis with large shell deformation. The experimental results of a rupturing model fuselage represented the variations in the mixed mode stress intensity factors, KI and KIIand the remote stress components σoxwith cracks extension. The crack kinking location, kinking angles and the off-axis crack trajectories are predicted by numerical analysis, and the validity of the calculated results is discussed in comparison with the experimental data.
