TL;DR: In this article, the authors investigated the influence of the orthotropy factor of structures upon all the buckling modes from global to local ones, and the uncoupled post-buckling state.
Abstract: Estimation of load carrying capacity on the basis of the post-buckling behaviour of thin-walled composite structures with imperfections is studied with the distortional deformations being taken into account. Our attention is focused on beams and corrugated trapezoidal plates subject to a constant bending moment or an axial compression, respectively. The structures are simply supported at the ends. The asymptotic expansion established by Byskov and Hutchinson (1977) is employed in terms of the numerical transition matrix method. The paper aims at to improving the study of the post-buckling equilibrium path of imperfect structures employing the second order non-linear approximation. The principal goal of numerical analysis is to investigate the influence of the orthotropy factor of structures upon all the buckling modes from global to local ones, and the uncoupled post-buckling state. In the solution obtained the transformation of buckling modes as the load increases up to the ultimate load and the shear-lag phenomenon are included.

TL;DR: In this article, an elastic double-shell model is presented for the pure bending buckling of a double-walled carbon nanotube, and a condition is derived in terms of the buckling modes of the shell, from which the critical bending moment can be predicted.

TL;DR: In this paper, a weighted residual approach for differentiating one-dimensional discrete data is presented and applied to an experimental program in which distributions of bending moment were measured along a model pile foundation in a centrifuge test.
Abstract: A weighted-residual approach for differentiating one-dimensional discrete data is presented and applied to an experimental program in which distributions of bending moment were measured along a model pile foundation in a centrifuge test. The weighted-residual approach is validated by first differentiating a sinusoidal bending moment distribution, and errors in first and second derivatives associated with various ratios of wavelength to sampling interval are computed. A bending moment distribution from a finite-element simulation of a pile foundation is differentiated using the weighted-residual technique, by fitting cubic splines, and by polynomial regression, and second derivatives are compared with the recorded subgrade reaction distributions. The influence of adding noise to the sampled bending moment distribution prior to differentiation is explored and is found to be most influential when sampling intervals are small. Bending moment data recorded during the centrifuge experiment are double differenti...

TL;DR: In this article, the bending performance of triangular plate elements with only three translational degrees of freedom per node in which the out-of-plane degree of freedom is the only displacement considered is investigated.
Abstract: This investigation assesses the bending performance of triangular plate elements with only three translational degrees of freedom per node in which the out‐of‐plane degree of freedom is the only displacement considered. A review is presented of three element formulations followed by the results of a series of case studies which illustrate the element behaviour. Results obtained from elastic theory and finite element analysis using more complex element formulations are given for comparative purposes.
