“…[30] The uniaxial local critical buckling load of composite plate reinforced by CNT is calculated and also their results are compared with the obtained FEM results by Ghorbanpour et al [31] that are shown in Table 3 for different volume fraction of CNT. It can be observed that the analytical results are quite close to the numerical results.…”

In this article, the surface stress effect on the biaxial critical buckling load of nonlocal polymeric nanocomposite rectangular plate reinforced by carbon nanotubes (CNTs) is presented. Various approaches such as Eshelby-Mori-Tanaka, the extended mixture rule, Halpin-Tsai, and micromechanical are used to determine the effective material properties of polymeric nanocomposite plate. The governing equations of equilibrium are obtained by using Hamilton's principle. The Navier's method is considered to obtain the biaxial critical buckling load of polymeric nanocomposite rectangular plate for simply supported boundary conditions. A detailed parametric study is conducted to explain the effects of aspect ratio, elastic foundation, surface stress and agglomeration on the biaxial buckling of nanocomposite plate. The results show that surface stress effect plays an important role at nanoscale. Also, the biaxial critical buckling load decreases with increasing the CNTs volume fraction in the inclusion (agglomeration effect). The results of this research can be used for micro-electro-mechanical and nano-electro-mechanical devices.

“…17,18 In the last decades, many researchers have focused on the buckling to overcome this serious problem in laminated composite structures. Hybrid nanocomposite laminates are one of the new and superior laminated structures that have high strength and mechanical properties and also thin thickness and low weight at the same time.…”

This article experimentally investigates the buckling strength of carbon fiber-reinforced polymer laminates. Samples were made with 16 layers of carbon fibers in four orientations of 0°, 30°, 60°, and 90°. Nano silica (SiO 2 ) and nano clay were used as fillers for enhancement of the buckling strength of carbon fiber-reinforced polymer laminates. The Taguchi method was used for design of experiments and optimizing the three input factors: nano silica, nano organoclay, and carbon fiber orientation. From the results, first, it was found that the most buckling strength belonged to the samples with the fiber orientation of 0°and the minimum strength belonged to the composite laminates with the 90°orientation of carbon fiber. Second, the use of two nano fillers in quaternary laminates (epoxy/carbon fiber/silica/clay) has increased the buckling strength of laminates about 45.5% and 22.5% in comparison with binary and ternary laminates, respectively. The binary laminates were made from carbon fiber/epoxy resin and the ternary laminates included carbon fiber/clay/epoxy. Third, the elastic modulus of laminates increased with an increase in the nano SiO 2 content. The most effective parameters according to the analysis of variance results were as follows: carbon fiber orientation, nano silica, and nano organoclay, with a probability value of 99%, 95%, and 90%, respectively. Finally, the analytical analysis was done according to the classical laminated plate theory for obtaining the buckling force and verifying and comparing the results with experimental buckling tests. The results obtained from classical laminated plate theory for two certain laminates were in excellent agreement with those obtained from experimental results.

“…Chen and Kim [3] utilized a combined equivalent energy method and proposed a stretched corrugated plate model. Numerical methods, such as finite element method, can solve particular structures (e.g., crack propagation in a bearing ring [4], blast loaded corroded plates [5] and stretched corrugated beam elements [6]) and have provided solutions to highly complex problems encountered in plate buckling, such as laminated composite plates under compression [7], partially compressed plate [8], and defective plate under shear [9], uniform compression [10,11] and local compression [12].…”

Uniformly stretched thin plates do not buckle unless they are in special boundary conditions. However, buckling commonly occurs around discontinuities, such as cracks, cuts, narrow slits, holes, and different openings, of such plates. This study aims to show that buck-ling can also occur in thin plates that contain no defect or singularity when the stretching is local. This specific stability problem is ana-lyzed with the finite element method. A brief literature review on stretched plates is presented. Linear and nonlinear buckling stress analyses are conducted for a partially stretched rectangular plate, and various load cases are considered to investigate the influence of the partial loading expanse on the critical tensile buckling load. Results are summarized in iso-stress areas, tables and graphs. Local stretch-ing on one end of the plate induces buckling in the thin plate even without geometrical imperfection.
