“…This aim was modeled by Al Qablan and Hazim Dwairi through Eigen-buckling analysis that is performed for the laminated composite plates which take into consideration higher-order shear deformation theory, through the use of the finite element package named Abaqus et al [6] and Vandenbrink and Kamat [23] They also found that the buckling load of composite plates with large holes begin to increase above that of the corresponding solid plate for fiber orientation angle of 60°. While experimentally, compression tests were performed on to 16 fiber-glass laminated plates with and without circular cut-outs Nomenclature q density (g/cm 3 ) m Poisson's ratio E 11 Young's Modulus in x direction (Pa) E 22 Young's Modulus in y direction (Pa) E 33…”

“…Also, an increase of the length/thickness ratio of 50% increases the buckling load in the range of 75%. Hu and Lin [21] they also presented an optimization scheme with respect to fiber orientation for the buckling load of symmetrically laminated plates with central holes Baltaci et al [22] analyzed laminated circular plates with circular holes using finite element analysis. They concluded that the critical buckling load decreases as the hole gets closer to the plate center.…”

a b s t r a c tThis paper presented the effect of cutout hole on multi layer of Kevlar-29/epoxy composite laminated plates this effect occurred and fiber orientation angle. An experimental procedure was developed to study the performance of these effects under quasi-static compressive and tensile load using a servo-hydraulic testing machine. The work involved investigation on the variety of orientation angles of Kevlar-29 fiber. The ultimate load of failure for each Kevlar-29/epoxy laminated plates had been determined and specified the optimum angle orientation and the load reduction due to the effect of fiber orientation angle (+45°/À45°) was low in the case for compared (0°/90°) orientation angle of fiber. To simulate this problem the researcher used Explicit Mesh for AUTODYN under ANSYS-12.1 software, where the researcher found that the results obtained via this simulation agreed reasonably well with the experimental results and the maximum difference between the experimental conditions and the simulation was 5.8%.

The aim of this numerical and statistical study was to investigate the buckling analysis of laminated composite plates containing functionally graded fiber orientation angles. The laminated composite plates had functionally graded fiber orientation angles based on Taguchi’s L18 (21 × 32) orthogonal array. The fiber orientation angles were considered to be control factors. Numerical analyses were performed using finite element software ANSYS. The optimum critical buckling load and the effects of fiber orientation angles for maximum data were determined using the analysis of the signal-to-noise ratio. The importance levels of laminates and their percent contribution on the buckling characteristics were calculated using analysis of variance. Regression analysis was employed to investigate the effects of control factors on buckling responses mathematically. The effects of laminate stacking sequence, mesh size, element type, mode number, and boundary condition were carried out using laminates with the optimum levels.

“…buckling and post-buckling behaviour of thick plates under uniaxial and biaxial compressive loading. Laminated composite plates with geometrical discontinuities in the form of holes have been considered for buckling response analysis in the past few decades [2][3][4][5][6][7][8][9]. Baba and Baltaci [2] compared their numerical and experimental results for buckling analysis of laminated composite plates with central cutouts and found that the experimental value of buckling load was higher than numerical predicted load owing to the imperfection in the experimental test specimen.…”

In this study, buckling characteristics of laminated composite plates with different shapes of holes under uniform/nonuniform mechanical and thermal loads are investigated. Mathematical formulations are done using finite element-based first-order shear deformation theory. A MATLAB programme is developed using isoperimetric quadrilateral elements with five degrees-of-freedom per node. Uniaxial and biaxial loading on full and partial edge of the plate are considered in the analysis. Solution for buckling load is done using eigenvalue approach and detailed parametric studies revealed the influence of the aspect ratio, plate span to thickness ratio, the shape of hole, distribution of mechanical and thermal load, boundary conditions, and fibre orientation on buckling loads and temperature. The findings of this study are in good agreement with those presented in the literature, verifying the efficiency of the proposed method.
