An Assessment of the Eurocode 3 Simplified Formulas for Distortional Buckling of Cold-Formed Steel Lipped Channels

Applied Sciences
This paper concerns the Eurocode 3 Part 1-3 (EN 1993-1-3) methods for calculating the distortional buckling (bifurcation) load of cold-formed steel-lipped channels subjected to axial force, major and minor axis bending.

Free-Vibration and Buckling Analyses of Beams using Kriging-Based Timoshenko Beam Elements with the Discrete Shear Gap Technique

Civil Engineering Dimension
A family of locking-free Kriging-based Timoshenko beam elements with a new implementation of the discrete shear gap technique was recently developed (referred to as K-beam-DSG1 elements). Performance of the K-beam-DSG1 elements has been shown to be very

Bifurcations of a simplified buckling problem and the effect of discretizations

manuscripta mathematica, 1991
The author gives a detailed description of bifurcations on the trivial solution branch \(\{\) (0,\(\lambda\)); \(\lambda\in {\mathbb{R}}\}\) of a simplified buckling problem \(\Delta u+\lambda \sin u=0\) in \(\Omega =[0,1]\times [0,1]\), \(u=0\) on \(\partial \Omega\).

Double-eigenvalue bifurcation and multistability in serpentine strips with tunable buckling behaviors

Journal of the Mechanics and Physics of Solids
Serpentine structures, composed of straight and circular strips, have garnered significant attention as potential designs for flexible electronics due to their remarkable stretchability. When subjected to stretching, these serpentine strips buckle out of plane, and previous studies have identified two distinct buckling modes whose order of appearance ...

Least-squares Smoothed Shape Functions for Constructing Field-Consistent Timoshenko Beam Elements

Civil Engineering Dimension
This paper presents an approach for constructing field-consistent Timoshenko beam elements using least-squares smoothed (LSS) shape functions. The variational basis for shear strain redistribution is thoroughly explained, leading to the derivation of ...
