TLDR
In this article, the postbuckling response of a simply supported thin-walled beam subjected to an axial compressive load and supported by the Winkler-Pasternak foundation is studied.Abstract:
The problem of the post-buckling response of a simply supported thin-walled beam subjected to an axial compressive load and supported by the Winkler–Pasternak foundation is studied in this paper. The strains are assumed to be small and elastic. The shear deformations and the in-plane cross-sectional deformations are assumed to be negligible. The post-buckling paths of the simply supported beam are determined for different values of the Winkler and Pasternak stiffness parameters. Bifurcation points are found.read more

Quasi-Harmonic Bending Waves Evolution in a Beam Lying on the Generalized Nonlinear-Elastic Foundation and Possibility of their Transformation into a Sequence of Wave Packets
TL;DR: In this article , a generalized base model is selected that contains two independent bed coefficients: stiffness for tensile (compressive) and shear deformations, and the model assumed dependence on the transverse midline beam and its gradient displacement.

Accurate Solution for Orthotropic Beams with Continuously Variable Cross Sections
TL;DR: In this paper , the exact stress distribution of simply supported beams of any thickness is determined by performing a Fourier sine series expansion upon the bottom and top surfaces of the beam.
