Experimental and Numerical Study on the Lateral-Torsional Buckling of Steel C-Beams with Variable Cross-Section

Metals, 2018
Metallic thin-walled beams with continuously varying cross-sections loaded in compression are particularly sensitive to instability problems due to lateral-torsional buckling. Such a phenomenon depends on several parameters, including the cross-sectional

NUMERICAL SIMULATION OF A THIN-WALLED BEAM WITH WARPING STIFFENERS UNDERGOING TORSION

TASK Quarterly, 2002
A new approach to numerical simulation of behavior of thin-walled beams of open crosssection with some warping stiffeners is presented. The structure model consists of one-dimensional finite elements described by the standard theory of thin-walled beams

Integral Method for Structural Analysis of Beams with Bending-Torsion Coupling [PDF]

INCAS Bulletin, 2018
This paper deals with structural static or stability analysis of straight beams, when the bending-torsion coupling is considered. A practical case is the lateral buckling analysis of high cross-section beams which involves the coupled bending deflection ...

Models of Thin-Walled Beam Connections [PDF]

, 1992
In thin-walled beam theory the kinematics of the beam is described by 6 degrees of freedom for a rigid body displacement of each cross-section plus an additional degree of freedom for cross-section warping. Torsion and warping are coupled, and this coupling requires special attention at joints.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Lateral stability analysis of steel tapered thin-walled beams under various boundary conditions [PDF]

Numerical Methods in Civil Engineering, 2018
The lateral-torsional buckling of tapered thin-walled beams with singly-symmetric cross-section has been investigated before. For instance, the power series method has been previously utilized to simulate the problem, as well as the finite element method.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...
