Crucial buckling loads of composite laminates are typically determined by employing analytical techniques based on the presumptions that the plates are susceptible to uniform edge loads, ignoring the fact that the practical assemblies are regularly exposed to different non-uniform edge loads. The current research paper is centered on the buckling behaviour of different patterns of trapezoidal composite laminates with cutouts under the application of non-uniform in-plane edge loads by employing finite element technique. To achieve this, the panel is discretized by using 9-noded heterosis plate element by employing the impact of shear deformation and rotary inertia. For a given load and the shape of panel, the stress concentration within the panel is highly non-uniform in nature. Hence, a dynamic approach has been employed to calculate the buckling loads. The accuracy of the method is verified by relating the obtained results with existent research. The impact of various variables including the size of the cutout, non-uniform edge loads, boundary conditions, ply alignments and panel trapezoidal shape ratio has been considered to examine the buckling behavior of trapezoidal panels. Buckling load factor optimization using CCD and RSM has also been carried out in detail.

The solution for the buckling problems of fibre metal laminates is usually based on the assumptions that the plates are subjected to uniform edges loads without any discontinuity or damages. Nevertheless, in practice the plates are subjected to various kinds of nonlinear/nonuniform edge loads along with various sized and positioned openings. The present work mainly focused on the vibration and buckling performance of inter laminar hybrid fiber metal laminates (HFMLs) with and without cutouts subjected to different kinds of nonlinear loading conditions by utilizing finite element approach. Towards this a 9-noded heterosis plate element has been used to discretize the plate by taking into account the effect of shear deformation and rotary inertia. Since the stress distribution within the plate is highly non-uniform in nature, the dynamic approach has been used to solve the buckling problems. The present study consists of aluminum metal face sheets bonded with four layered symmetric hybrid cross-ply laminates, in which six different hybrid configurations have been considered. The performance of each hybrid configuration along with different sized and positioned cutouts is well investigated under various nonlinear loading conditions.
