| Abstract: | A versatile 4-node plate element
of Mindlin plate theory is used in this paper. The disturbing energy method is used to
determine the critical loads for plate bucking, and a corresponding energy criterion is
presented for plates at loss of stability. The results of numerical examples show that
this method is feasible and versatile. |

| Keywords: | plate element stability analysis disturbing energy criterion critical load |
