AXIAL BUCKLING ANALYSIS OF FUNCTIONALLY GRADED PLATES (AL/AL2O3) USING NAVIER METHOD

In the present paper, exact solution of the axial buckling analysis to the functionally graded materials plates (Al/Al2O3) is studied. Using a four variable refined plate theory, both a quadratic variation of the transverse shear strains across the thickness and the zero traction boundary conditions on the top and bottom surfaces of the plate is satisfied without using shear correction factors, from the principle of minimum total potential energy, we obtain the governing equations. The number of independent unknowns of present theory is four, as against five in other shear deformation theories. Numerical examples on the buckling analysis of functionally graded plate demonstrate the accuracy of the present approach.
