Origami has played an increasingly central role in designing a broad range of novel structures due to its simple concept and its lightweight and extraordinary mechanical properties. Nonetheless, most of the research focuses on mechanical responses by using homogeneous materials and limited studies involving buckling loads. In this study, we have designed a carbon fiber reinforced plastic (CFRP) origami metamaterial based on the classical Miura sheet and composite material. The finite element (FE) modelling process’s accuracy is first proved by utilizing a CFRP plate that has an analytical solution of the buckling load. Based on the validated FE modelling process, we then thoroughly study the buckling resistance ability of the proposed CFRP origami metamaterial numerically by varying the folding angle, layer order, and material properties, finding that the buckling loads can be tuned to as large as approximately 2.5 times for mode 5 by altering the folding angle from 10° to 130°. With the identical rate of increase, the shear modulus has a more significant influence on the buckling load than Young’s modulus. Outcomes reported reveal that tunable buckling loads can be achieved in two ways, i.e., origami technique and the CFRP material with fruitful design freedoms. This study provides an easy way of merely adjusting and controlling the buckling load of lightweight structures for practical engineering.

“…Torabizadeh and Fereidoon [59] used CLPT and the first-order shear deformation plate theory (FSDT) to derive governing equations of the laminated composite plates. The results were shown that the fundamental frequency increased with the modular ratio for both cross-ply and angle-ply laminates with the CLPT.…”

It is a challenging target to improve the dynamic analysis and free vibration analysis of fiber metal laminates (FMLs) while providing great promise as lightweight structural components. FMLs have attracted increasing research interest in various multi-stack FML components to enlarge industrial applications. This review paper concentrates on the free vibration analysis of FMLs, which mainly refers to dynamic analysis, macro mechanical and micro mechanical approaches, and temperature effects. The available types of experimental vibration methods on FMLs are described. Moreover, dynamic analysis of FMLs is mainly reviewed in recent studies of FMLs on the macro mechanical and micromechanical scale aspects, and the temperature effect is also studied. Furthermore, several classical theoretical equations of different FMLs on free vibration analysis are summarized. In addition, optimization studies on FMLs under dynamic analysis are further discussed.

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.
