“…The high values of NF could not be predicted by previous methods in the literature, such as ZZT and local-global models. Furthermore, Thakur et al [431] employed the higher-order nonpolynomial shear deformation theory (HNPSDT) to develop a C0 FE modeling to investigate the dynamic performance of a folded LCP. The IHSDT combined with nine-nodded Lagrange isoparametric FE, while the HP has been utilized to drive the GEs, and the subspace iteration method (SIM) has been implemented to solve the FV referred to as the eigenvalue problem.…”

Recently, the mechanical performance of various mechanical, electrical, and civil structures, including static and dynamic analysis, has been widely studied. Due to the neuroma's advanced technology in various engineering fields and applications, developing small-size structures has become highly demanded for several structural geometries. One of the most important is the nano/micro-plate structure. However, the essential nature of highly lightweight material with extraordinary mechanical, electrical, physical, and material characterizations makes researchers more interested in developing composite/laminated-composite-plate structures. To comprehend the dynamical behavior, precisely the linear/nonlinear-free vibrational responses, and to represent the enhancement of several parameters such as nonlocal, geometry, boundary condition parameters, etc., on the free vibrational performance at nano/micro scale size, it is revealed that to employ all various parameters into various mathematical equations and to solve the defined governing equations by analytical, numerical, high order, and mixed solutions. Thus, the presented literature review is considered the first work focused on investigating the linear/nonlinear free vibrational behavior of plates on a small scale and the impact of various parameters on both dimensional/dimensionless natural/fundamental frequency and Eigen-value. The literature is classified based on solution type and with/without considering the size dependency effect. As a key finding, most research in the literature implemented analytical or numerical solutions. The drawback of classical plate theory can be overcome by utilizing and developing the elasticity theories. The nonlocality, weight fraction of porosity, or the reinforcements, and its distribution type of elastic foundation significantly influence the frequencies.

This paper presents the advantages of carbon nanotubes (CNTs) in fortifying the glass fiber reinforced polymeric (GFRP) composites. Bolted steel straps are utilized at the edges of composite plate to create clamped conditions in the test setup. To reduce the uncertainties induced by bolt attachments, a genetic algorithm based model updating has been carried out by adopting artificial linear springs at the margins to create more balance between theory and reality. After checking the validity of plate's results, mechanical properties of randomly dispersed CNTs are incorporated in the formulations of folded plates. Remarkably, the motion equations are brought forward by the first order shear deformation theory (FSDT). Thereafter, two-directional generalized differential quadrature (2D-GDQ) technique has been used to extract natural frequencies from available motion, continuity and boundary equations. Results of the folded plate are validated first by an experimental modal testing and then some effective parameters such as folding angle, CNT weight ratio, boundary condition and flange-shape length are inspected.

“…(Vidal et al 2019) investigated the free vibration analysis of laminated composite plates by using a variable separation approach. (Thakur et al 2020) employed an efficient C0 finite element modeling combined with higher-order nonpolynomial shear deformation theory to investigate the natural frequencies and to perform a transient analysis of the laminated composite folded plates having different fiber angles, fold location, crack angle, lamination scheme, and boundary conditions. (Rezaiee-Pajand et al 2020) performed free vibration analysis of functionally graded hybrid matrix/fiber nanocomposite conical shells employing the First-Order Shear Deformation Theory.…”

This study presents the dynamic and buckling analysis of the laminated composite thin arch plate frame structures employing Classical Plate Theory with Finite Element Analysis. For this purpose, The effects of the radius of curvature, aspect ratio, and stacking order of such structures on the first ten natural frequencies, mode shapes, critical buckling load, and the first unstable regions are investigated. Besides, the two-bay curved plate frame structure is investigated. In order to perform dynamic and buckling analyses, a computer code is developed and executed via MATLAB. The results are compared and validated with those of ANSYS. It is concluded that the aspect ratio or the stacking order affects the dynamic characteristics of the curved plate frame structure considerably while the radius of curvature relatively has less impact on such dynamic properties of the structure.
