The Influence of Boundary Conditions on the Buckling of Stiffened Cylindrical Shells.

摘要

Theoretical and experimental studies on the influence of boundary conditions on the buckling of stiffened cylindrical shells and their vibrations are discussed. The effect of prebuckling deformations on the buckling loads and vibrations of stiffened shells is studied and compared with that in the case of unstiffened shells. The in-plane boundary conditions are found to be of particular importance for stiffened cylindrical shells and their effect differs significantly from that in unstiffened shells. The effect of axial restaints, which are found to be of prime importance in stringer-stiffened shells are also studied.
