Studying enhancement of Buckling of composite 2D-FG Cylindrical Shellsproduced by Alumina and Aluminum elements

This paper has been proposed to investigate enhancement in Buckling of two-dimensional functionally graded (2DFG) cylindrical composite shells using Alumina and Aluminium elements under combined loads based on first-order shear deformation theory (FSDT). Features of this composite are changing in both radial and axial directions. The material properties composite are graded in two directional (radial and axial). The Euler’s equation is employed to derive the stability equations which have been solved by numerical method. In the following, the effects of shellgeometry, the mechanical properties and elements distribution in radial and axial directions on the mechanical critical buckling loads of cylindrical shell are studied and it is compared with a cylindrical composite shell made of one-dimensional functionally graded material (1D-FGM). The numerical results reveal that the composite materials (2D-FGM) in which Alumina and Aluminium elements are used in have a significant and crucial effect on improvement of the critical buckling load.
