A numerical and experimental study was carried out to determine the effects of anti-symmetric laminate configuration, cutout and length/thickness ratio on the buckling behavior of E/glass-epoxy composite plates. The buckling loads were presented for symmetrically and anti-symmetrically laminated plates subjected to axial compression load. The study included two different laminate configurations ([90/45/−45/0] as and [90/45/−45/0] s ), two different cutout shapes (circular and semi-circular), two different length/thickness ratios (L/t=75 and 37.5) and three boundary conditions (clamped-clamped [CC], clamped-pinned [CP] and pinned-pinned [PP]). Firstly, the buckling loads of eight-ply E/glass-epoxy rectangular plates were determined experimentally. Then, the buckling loads of the laminated composites were calculated by ANSYS finite-element computer code. The changing in buckling load of the composites due to the presence of cutout and changing of length/ thickness ratio was calculated. Finally, the experimental test results were compared to the buckling loads of plates obtained from the finite element analysis.

“…Vanden Brink and Kamat [5] presented a finite element analysis for the isotropic and laminated composite square plates with circular holes. Applying finite element and perturbation methods, Larsson [ 6 ] investigated buckling of orthotropic compressed plates with circular holes. Using the finite element method for computing in-plane stress, Uenaya and Rewood [ 7 ] determined the shear buckling of square plates with holes by the aid of the Rayleigh-Ritz method.…”

Abstract-In this study, an investigation of buckling analysis which includes geometric and material effects on critical load of thermoplastic-matrix composite plates with square hole is carried out by using finite element method (FEM). A finite element computer program is developed for finding critical loads. The composite plates2 ) under transverse loading are formed by stacking four composite layers bonded symmetrically or antisymmetrically. Each layer with constant thickness is meshed into 48 elements and 228 nodes.The first-order shear deformation theory is employed in mathematical formulation. the effects on critical load by ply lamination geometry, plate thickness ratio, loading types, hole size, and material modulus ratio have been investigated. Numerical solutions are given in graphical forms.
