Local buckling of cracked and pin-loaded plates

The interaction between buckling and fracture may affect crack growth in thin riveted aircraft fuselage structures, Buckling may also complicate and induce the phenomenon of multisite damage in aircraft fuselages, This buckling-fracture phenomenon in thin-walled structures is studied through an idealized model, a cracked and pin-loaded hole in a plate, Despite this simplification, a better understanding of the mechanisms of fatigue and fracture in thin-walled structures is obtained by a finite element model and an experiment, using holospeckle interferometry. The experimental studies show an interesting phenomenon, the presence of a combination of tearing mode III as well as opening mode I fracture mechanisms at the cracks in the pin-loaded plates after local buckling,This phenomenon is discussed, and further research is foreshadowed.
