Elastic Stability of Annular Thin Plates with One Free Edge

Abstract EN

The elastic stability of annular thin plates having one free edge and subjected to axisymmetric radial edge loads at the other edge is investigated.

The supported edge is allowed to be either simply supported or clamped against axial (transverse) deflection.

Both compression buckling and tension buckling (wrinkling) are investigated.

To insure accuracy, two methods of solving the appropriate eigenvalue problems are used and found to yield essentially identical results.

A selection of these results for both compression and tension buckling is presented graphically and used to illustrate interesting aspects of the solutions.
