“…The ceramic is used to greatly enhance the thermal and corrosion resistance, while the metal is responsible for improving the mechanical properties such as fracture toughness, load carrying capacity, and modulus of elasticity. Although some previous research focused on the buckling analysis of FGM plates [27][28][29][30][31], only a few studied the effect of openings in the geometry on the buckling of the plates [40,41]. Generally, the need for openings in plates is vital in order to facilitate the passage of some service pipes.…”

“…Interestingly, the results for AL/Al 2 O 3 and Al/SiC FGM plates were identical. Swaminathan et al [28] studied the vibration and buckling characteristics of FGM panels subjected to uniaxial and biaxial conditions using the finite element method (FEM). It was observed that the plate is less vulnerable to buckling when the load is applied at the edge of the plates.…”

In this paper, an investigation of linear eigenvalue buckling of functionally graded material (FGM) plates under uniaxial loading is carried out. The computer model is analyzed using the finite element (FE) package ABAQUS. An analysis is carried out to study the effect of the size and geometry of openings in the FGM plate on the critical buckling load. The circular, square, and diamond openings vary in size based on the ratio of the opening diameter to the width of the FGM plate. Moreover, the effect of the aspect ratio (width to thickness) of the FGM plate on the critical buckling load is examined. Further, the effect of the power law index on buckling behavior is investigated. The results show that the increase in the size of the opening and the aspect ratio reduces the critical buckling load of the FGM plate. Moreover, the lower the power law index, the higher the critical buckling load. The diamond shape opening shows the best performance in terms of the critical buckling load, and the effect of the plate thickness has a more significant influence on the critical buckling load of the FGM plate compared to the size of the opening.

“…Most of the buckling studies of composite laminated plate are carried out under uniform compressive edge loads. [5][6][7][8][9] In the real time scenario, uniform loads are very trivial in nature. Therefore, analyzing the plate under nonlinear/non-uniform edge loads is very much needed in the real time applications.…”

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.
