Buckling of an annular sector plate subjected to equal and opposite moments at the radial edges examined. The governing differential equation of the plate is solved by a Galerkin method. Buckling moments and buckling modal shapes are obtained for annular sector plates with radial edges simply supported and arbitrary boundary conditions along the circular edges. Numerical results are shown for various boundary conditions along the circular edges and geometrical parameters of the annular sector plate and are compared with the buckling moments of the rectangular plate.
