In the present article, buckling and deflaction analysis of functionally graded annular thin and moderately thick plates under mechanical loads is investigated. Solving the decoupled equations and satisfying the boundary conditions yield an eigenvalue problem to find the critical buckling load and deflection. Finally, the effects of annularity, plate thickness and power law index on buckling load and deflaction of functionally graded annular plates are investigated and the buckling mode shapes are plotted
