Add to ORKGExperimental results on CFRP curved stiffened panels subjected to several combinations of axial compression and shear loading are presented and discussed. Panels are assembled in a closed box configuration so to have a shear load by applying a torque on the box. Six static tests are initially carried out for evaluating the response of the box to static post-buckling load. Then several combined cyclic tests are performed at different torque load levels in order to analyze the effect of the repetition of a post-buckling load on the global behavior of the specimen. Presented results clearly demonstrate, from one hand, the capability of CFRP panels to work in the post-buckling range without any damage and, from the other hand, their possibility...
