“…The reduction of Young's modulus for the specimen with 9 percent nanoclay can also be observed from It is worth mentioning that during the preparation of specimens, intercalation and exfoliation processes have to be carried out carefully to avoid agglomeration phenomena. The reduction of maximum contact force and Young's modulus can be due to the sticking of nanoparticles together and agglomeration phenomenon (Wuite and Adali, 2005). As can be inferred from the experimental data tabulated in Table3 and results of this study from Table 4, the increase percentage of the maximum contact force is lower than the increase percentage of Young's modulus.…”

“…Vibration analysis of a functionally graded carbon nanotube-reinforced beam was reported (Heshmati and Yas, 2013;Ke et al, 2010;Yas and Heshmati, 2012). Wuite and Adali (2005) examined the deflection and stress in a nanocomposite carbon/polyester/nanotube beam subjected to a concentrated force at the beam center. They analyzed the beam using classical laminate theory and did not incorporate Hertz's law in their analysis.…”

Low-velocity impact of a nanocomposite beam made of glass/epoxy reinforced with multi-wall carbon nanotubes and clay nanoparticles is investigated in this study. Exerting modified rule of mixture (MROM), the mechanical properties of nanocomposite including matrix, nanoparticles or multi-wall carbon nanotubes (MWCNT), and fiber are attained. In order to analyze the lowvelocity impact, Euler-Bernoulli beam theory and Hertz's contact law are simultaneously employed to govern the equations of motion. Using Ritz's variational approximation method, a set of nonlinear equations in time domain are obtained, which are solved using a fourth order Runge-Kutta method. The effect of different parameters such as adding nanoparticles or MWCNT's on maximum contact force and energy absorption, stacking sequence, geometrical dimensions (i.e., length, width and height), and initial velocity of the impactor have been studied comprehensively on dynamic behavior of the nanocomposite beam. In addition, the result of analytical model is compared with Finite Element Modeling (FEM).The results reveal that the effect of nanoparticles on energy absorption is more considerable at higher impact energies.

Abstract:In this paper presents bending characteristic of multi-layered carbon nanotube reinforced functionally graded composite plates. The finite element implementation of bending analysis of laminated composite plate via well-established higher order shear deformation theory (HSDT). A seven degree of freedom and C 0 continuity finite element model using nine noded isoperimetric elements is developed for precise computation of ply-by-ply deflection and stresses of laminated Single Wall Carbon Nanotube Reinforced composite plate subjected to uniform transverse loading. The finite element implementation is carried out through a finite element code developed in MAT-LAB. The results obtained by present approach are compared with results available in the literatures. The effective material properties of the laminated SWCNTRC plate are used by Mori-Tanaka method. Numerical results have been obtained with different parameters, width-to-thickness ratio (a/h), stress distribution profile along thickness direction, different SWCNTRC-FG plate, boundary condition and various lamination schemes.

“…As such, there is a need to examine the macro behavior of the material in actual structural elements such as beams and plates. The behavior of beams under a static loading was studied by Wuite and Adali (2005) for different CNT volume of fractions and nanotube diameters. Based on different assumptions for displacement fields, different theories for plate analysis have been devised.…”

Most plates used in engineering structures such as aircraft wings, ship ducts and buildings, although quite capable of resisting tensile loads, are poor in withstanding compression. In order to avoid premature failure under compression, it is important to know buckling behavior of the plate. This article primarily deals with the analytical study of buckling behavior of a carbon nanotube reinforcing polymer composite plates based on the first order shear deformation theory by employing Mori-Tanaka micromechanics approach to obtain elastic properties. In this investigation, an attempt is made for evaluating the effect of plate thickness, CNT volume fraction, stacking sequence and CNT radii on the buckling of plates.
