Abstract
In this paper, a numerical study was performed in a curved panel to evaluate the effect of the closed section ribs on the local buckling strength of the isotropic material. This study performed a 3-D finite element modeling and eigenvalue analysis to the curved panel stiffened by closed section ribs using a general structural analysis program ABAQUS, and the numerical analyses were conducted with varying thickness and radius of curvature. The parametric analysis result showed that as the radius of curvature decreases, the buckling strength of the curved panels increases. In addition, the result showed that the dominant failure mode of the curved panel should be a local plate buckling in the effective width between the stiffeners when closed-section ribs hold a sufficient bending stiffness. Therefore, the local buckling strength of the curved panel stiffened by closed-section ribs under in-plane axial compression could be rationally evaluated by applying the spacing between the closed-section ribs as the effective width and by simultaneously taking into consideration the influence due to the U-ribs' rotational stiffness and the radius of curvature of curved panels.
