摘要：

This paper deals with elastic stability of annular plates under uniform radial loads applied at its edges; emphasis is set oil the analysis of nonaxisymmetric buckling forms. In order to increase the buckling strength a circular support is laid to the plate. Three loading types are considered. The stability equation is put together and integrated by separating the variables. Such a location of the support for which the buckling strength is maximal is sought. Calculations are carried out for plates with clamped edges.
