Instability of Thin Walled Bars

Journal of Engineering Mechanics, 1983
Energy equations governing the flexural, torsional, and lateral instability of thin walled bars of open cross section are derived. Shear deformations due to nonuniform bending, and distortion of the cross section are not considered, but the influence of pre‐buckling displacements is included in the analysis.

A consistent theory for torsion of thin-walled bars

Thin-Walled Structures, 1989
Abstract A consistent theory for torsion of thin-walled bars with cross-sections of arbitrary shape (open, closed or mixed) is developed in this paper; it is an improvement on the classical torsion theory of thin-walled bars. All the basic relations, formulas and equations are derived and proved under the consistent assumptions. A torsional stiffness

Nonlinear strains and instability of thin-walled bars

Journal of Constructional Steel Research, 2000
Abstract In this paper, the derivation of the nonlinear strains occurring in thin-walled bars of open cross-section, when subjected to axial, flexural and torsional displacements is reviewed and generalised. The nonlinear expressions for the strains are derived in accordance with beam theory, the influence of shear deformation due to non-uniform ...

Thin-Walled Bars

1988
There exists a great variety of possible buckling modes of thin-walled bars. Besides Euler’s buckling and lateral buckling we mention here, first of all, torsional buckling, and a combination of these phenomena. The above buckling modes, called jointly “the overall buckling”, may be investigated under the assumption of undeformable cross-sectional ...

Instability of Thin Walled Bars

Journal of Engineering Mechanics, 1985
Instability of thin walled bars of variable, open cross sections is analyzed. A thin walled bar is treated as a special case of the membrane shell with the internal constraints (Vlasov’s and Wagner’s assumptions). The geometry of the bar is described by means of coordinates of the discrete points located on the midsurface of the bar.
