“…Topal and Uzman [28] stepped on the path of modified feasible direction as an optimization routine to maximize natural frequencies of FSDT-based laminated folded plates. By defining very stiff springs at the specific locations of boundaries and intermediate supports, Jiang and Au [29] developed a general finite strip to be versatile in confronting with static and dynamic investigations of folded plates. Nguyen-Minh et al [30] also dealt with a cell-based smoothed discrete shear gap technique to explore the results of Mindlin folded plates statically and dynamically.…”

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.

“…Some highlighted numerical methods that have been proposed to analyze folded plate structures are the finite strip element methods [13][14][15][16], the combined boundary elementtransfer matrix method [17], the finite element method (FEM) [3,12,[18][19][20][21][22][23][24][25][26][27][28], the mesh-free Galerkin method [2,29]. Among these methods, the FEM, which is highly appreciated by the effectiveness and the extensibility for various problems, has taken much attention from researchers.…”
