Effect of Pressurization on the Buckling Behavior of Thin-Walled Cylinders Under Bending Load

This study deals with the buckling of thin cylindrical shells submitted to combined loads such internal pressure, bending and axial compression. A large experimental investigation is conducted and some explanations on the behavior of such loaded structures and on the influence of distinct parameters are gauged. The parametrical studies show the stabilising effect of low internal pressure and a drop of the load capacity for high internal pressure due to the plasticity effect. Specific recommendations are finally established for the design.
