Based on first order shear deformation theory (FSDT)‚ bending analysis of annular sandwich plates with functionally graded (FG) core is investigated using differential quadrature method (DQM). The plate has various edges boundary conditions and its material properties are assumed to vary in a power law with the Poisson ratio to be constant. The method is validated by comparing numerical results with the results obtained in the literature. The effect of the grading index on the bending behavior of annular sandwich plates with functionally graded core are investigated.
