In this video tutorial, we will learn about performing post buckling analysis of cylindrical shells under hydrostatic pressure in ANSYS Workbench. Also, we will see how to create pre buckled model of the cylindrical shell with the desired buckling mode and deformation scale factor for use in the post-buckling analysis. Cylindrical shells can fail due to compression in the longitudinal or circumferential direction, or due to shear. But usually, due to all of those effects combined in one way or another. Plus, this can happen locally or globally.
