"Buckling of an annular sector plate subjected to equal and opposite moments at the radial edges is examined. The governing differential equation of the plate is solved by a Galerkin method. Buckling moments and buckling modes are obtained for the annular sector plate with simply-supported radial edges and arbitrary boundary conditions along the circumferential edges.
Numerical results are shown for various geometrical parameters and three different boundary conditions. Moreover，the buckling properties of an annular sector plate are compared with those of a rectangular plate and a circular beam."
