    Three dimensional mechanical buckling of FG plates with general boundary conditions
    (Elsevier Sci Ltd, 2013) Uymaz, B.; Aydogdu, M.
    The mechanical buckling analysis of rectangular functionally graded plates under different axial loadings is considered. The analysis is based on the small strain elasticity theory with different boundary conditions. The material properties of the plate vary through the thickness direction according to a simple power law. Three dimensional buckling solutions are obtained using the Ritz method with Chebyshev polynomials as assumed displacement functions. The convergence and comparison studies are presented and effects of the different material composition and the plate geometry (side-side ratio, side-thickness ratio) on the critical buckling loads and mode shapes are investigated.

    Three dimensional shear buckling of FG plates with various boundary conditions
    (Elsevier Sci Ltd, 2013) Uymaz, B.; Aydogdu, M.
    In this paper, the buckling of functionally graded plates under shear are considered for various boundary conditions. The buckling results obtained by using Ritz method based on the three-dimensional linear elasticity theory and the higher order shear deformation theories. The material properties of the plate vary through the thickness direction according to a simple power law. The comparison results are presented and the variation of the critical shear buckling load and the critical shear buckling modes with the shear buckling characteristics like the material composition, the plate geometry parameters (side-side ratio, side-thickness ratio) are investigated.
