The problem of buckling of polar orthotropic annular plates under various types of inplane compressive forces along the radial edges has been analyzed in detail by the Rayleigh-Ritz method for eight different combinations of clamped, simply supported, and free boundary conditions. Accurate estimates of critical buckling loads have been obtained for various values of hole ratios and for various values of rigidity ratios. The numerical results are presented in the form of data sheets for direct use by the design engineers.
