Dynamic Buckling of Stiffened Panels
Procedia Engineering, 2015 AbstractDesignof stiffened panels requires evaluating their behavior under any loading circumstances by considering initial geometric imperfections and the altering effects resulting from eventual material degradation. Both static and dynamic loading scenarios are to be investigated in order to assess safety for buckling strength of these vital ...

Simulation of skin‐stiffener debonding in stiffened carbon/epoxy panels [PDF]
PAMM, 2007 AbstractAircraft fuselage structures are typically composed of a curved skin connected to longitudinal stiffeners. They are nowadays made of carbon/epoxy laminates. Skin‐stiffener debonding can lead to a significant reduction of their compressive loadcarrying capacity in the postbuckling range of response.
