WebBuckling patterns in thin plates and shells arise due to the relative ease of bending a thin sheet compared to stretching it, and take a variety of forms, from global wrin-kling to local folding and crumpling [1–3]. A particularly dramatic version of these patterns is seen in the buckling of axially loaded thin-walled cylinders; the reader ... WebFigure 9.4. Since we are interested in computing the critical buckling load, we will consider the beam to be at the onset of buckling.
