“…Reducing the wall slenderness increases the profile stability and buckling capacity exponentially [ 152 , 167 ], and shifts the failure mode from local buckling to material compressive failure due to the increase in the flexural stiffness of the laminated walls [ 170 , 185 ]. The effect of the wall slenderness was studied extensively for laminated plate geometry subjected to uniaxial compressive load [ 133 , 143 , 146 , 152 ] and the effect of the layup properties on the buckling load capacity of slender plates was found to be negligible compared to their dimensions [ 137 , 144 , 153 ]. This finding agrees with the results of parametric studies on open-section PFRP columns [ 67 , 81 , 114 ], shown in Figure 8 .…”

Review on Local Buckling of Hollow Box FRP Profiles in Civil Structural Applications

Hollow box pultruded fibre-reinforced polymers (PFRP) profiles are increasingly used as structural elements in many structural applications due to their cost-effective manufacturing process, excellent mechanical properties-to-weight ratios, and superior corrosion resistance. Despite the extensive usage of PFRP profiles, there is still a lack of knowledge in the design for manufacturing against local buckling on the structural level. In this review, the local buckling of open-section (I, C, Z, L, T shapes) and closed-section (box) FRP structural shapes was systematically compared. The local buckling is influenced by the unique stresses distribution of each section of the profile shapes. This article reviews the related design parameters to identify the research gaps in order to expand the current design standards and manuals of hollow box PFRP profiles and to broaden their applications in civil structures. Unlike open-section profiles, it was found that local buckling can be avoided for box profiles if the geometric parameters are optimised. The identified research gaps include the effect of the corner (flange-web junction) radius on the local buckling of hollow box PFRP profiles and the interactions between the layup properties, the flange-web slenderness, and the corner geometry (inner and outer corner radii). More research is still needed to address the critical design parameters of layup and geometry controlling the local buckling of pulwound box FRP profiles and quantify their relative contribution and interactions. Considering these interactions can facilitate economic structural designs and guidelines for these profiles, eliminate any conservative assumptions, and update the current design charts and standards.

“…The buckling loads were determined considering the base state of the structure—that is, the state of the load for which the eigenvalues are determined. In the base state, the structure may have initial loads P, stemming from previous analyses or initial conditions [ 2 , 7 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. The process of determining the critical force is divided into two stages.…”

The paper presents the optimisation of thin-walled composite structures on a representative sample of a thin-walled column made of carbon laminate with a channel section-type profile. The optimisation consisted of determining the configuration of laminate layers for which the tested structure has the greatest resistance to the loss of stability. The optimisation of the layer configuration was performed using two methods. The first method, divided into two stages to reduce the time, was to determine the optimum arrangement angle in each laminate layer using finite element methods (FEM). The second method employed artificial neural networks for predicting critical buckling force values and the creation of an optimisation tool. Artificial neural networks were combined into groups of networks, thereby improving the quality of the obtained results and simplifying the obtained neural networks. The results from computations were verified against the results obtained from the experiment. The optimisation was performed using ABAQUS® and STATISTICA® software.

“…The cross-ply composite plate is also stronger than any other angle-ply laminated plate analyzed. Ravi Kumar Pa et al [62] conducted a thorough analysis of stiffened and unstiffened plates with three various types of composite materials to determine the buckling load by the ANSYS software. It is concluded from the result that [0 0 /90 0 /45 0 /-45 0 ] fibre configuration yields the highest load, as the length to thickness ratio increases the load decreases, as the aspect ratio increases the critical load increases and critical load decreases in presence of cut-outs.…”

A composite material is generally a combination of materials differing in composition or form on a macro scale for the purposes of attaining specific characteristics and properties. The developments in the field of composite materials have granted significant weight reduction in structural design. When compared to metallic materials, composites offer many advantages, especially high strength, stiffness to weight ratio, excellent fatigue properties, and corrosion resistance. Plates, curved panels, the cylindrical shell-shaped forms of models are being broadly used in many structural packages of engineering structure. For design the structure, it is important to know the behaviour of these under static, free vibration, buckling condition. The present paper aims to review the literature on static, free vibration, and buckling analysis of composite flat panel, curved panel, and cylindrical shell. Further, the testing procedure of laminate, design guidelines of laminates and cost estimations with mechanical properties comparison of laminate with metal, CLT (classical lamination theory) basis including thermal and moisture expansion for stiffness evaluation are also summarised in this paper.
