On a generalized laminate theory with application to bending, vibration, and delamination buckling in composite laminates
… composite plates for the linear theory. Geometrical nonlinearity, including buckling and post-buckling are included and used to perform stress analysis of laminated plates. A general two-dimensional theory of laminated cylindrical shells is also developed in this study. Geometrical …

Nonlinear Analysis of Unsymmetric Laminates under Cylindrical Bending
… laminates. The <em>von-Karman</em> type geometrical nonlinearity is incorporated in the governing equation. The shear effect between lamina is further considered in the governing equation. The solution is obtained for different boundary conditions. The results of arbitrary angle-plies are …

Thermal Bending, Buckling and Post-Buckling Analysis of Unsymmetrically Laminated Composite Beams with the Effects of Moisture and Geometric Imperfections
… derived by taking into account the von-Karman geometrical nonlinearity for an imperfect unsymmetrical laminated composite beam. Classical beam theory (CBT) as well as first order shear deformation theory (FSDT) will be used. The effects of temperature, angle of orientation, moisture variations, …

Nonlinear dynamic behaviour of joined lightweight structures
… mechanism is allowed to interact with the geometrical nonlinearity of the beam or the plate model on a flexible support. Furthermore, for validation purposes, results from the plate model were compared to results from literature, experiments and some applicable analytical solutions. In …

Nonlinear Forced Vibration of an Unsymmetrically Laminated Composite Beam
… obtained by taking into account the von-Karman geometrical nonlinearity. These equations are transformed into nonlinear ODE (Ordinary Differential Equations) by means of the Galerkin method. For both cases the forced Duffing equation was obtained. It is to be noted that only for the …

Normal-strength and high-strength concrete columns under cyclic axial load and biaxial moment
… finite segment method and accounting for geometrical nonlinearity has been proposed here to predict the load-deflection curves of HSC columns under cyclical loading. The HSC stress-strain relationship obtained by parametric study and experimental investigation into the behavior of concrete …

Nonlinear vibration and chaotic motion of uniform and non-uniform carbon nanotube resonators.
… nonlinear vibration analysis of CNTs having geometrical nonlinearity and being rested on nonlinear Winkler and Pasternak foundations. The nonlinear vibrations of the curved CNTs are developed using the Eringen theory in conjunction with the Euler-Bernoulli beam model and the thermal effect is …

Reliability and failure analysis of composite beams and plates containing stress concentrations
… and analytically. For structures with geometrical irregularities such as notches, holes or cut-outs, no analytical solutions exist and approximate numerical schemes have to be employed. For this purpose, the finite element method is extensively used. For stress analysis of isotropic …
