Static analysis of annular sandwich plates with functionally graded core subject to an axisymmetric transverse load

Based on three-dimensional theory of elasticity static analysis of annular sandwich plates with functionally graded (FG) core is investigated using differential quadrature method (DQM). This method can give an analytical solution along the thickness direction using the state space method (SSM) and an effective approximate solution along the radial direction using the one-dimensional differential quadrature method. The plate has various edges boundary conditions and its material properties are assumed to vary in an exponential law with the Poisson ratio to be constant. The method is validated by comparing numerical results with the results obtained in the literature. The effects of the loading conditions, outer radius to inner radius ratio, and boundary conditions on the static behavior of annular sandwich plates with functionally graded core are investigated.
