Buckling Analysis of Orthotropic Laminated Composite Plate With Rectangular Cut-Outs By Using FEA

A finite element method using ANSYS software is used to determine the effects of square and rectangular cutouts on the buckling behavior of a 4-ply orthotropic carbon/epoxy symmetrically laminated rectangular composite plate. The square/rectangular cutouts were subjected to uniaxial compression loading. This study addresses the effects of the size of the square/rectangular cutout, orientation of the square/rectangular cutout, plate aspect ratio (a/b), on the buckling behavior of the symmetrically laminated rectangular composite plate under uniaxial compression loading. Buckling loads were computed for (0°/45°/45°/0°) orthotropic laminate configuration. Results showed that the magnitudes of the buckling loads decrease with increasing cutout positioned angle as well as c/b and d/b ratios for plates with a rectangular cutout. The magnitudes of the buckling loads of a rectangular composite plate with square/rectangular cutout decrease with increasing plate aspect ratio (a/b). The aspect ratio varied is from 2 to 6 in all the simulations. Further the nature of buckling load with respect to t/b ratio and the buckling factors at various t/b ratio's such as 1/20, 1/40, 1/60, and 1/80 is investigated using ANSYS software.
