Keywords: thin-walled beams, constitutive couplings, warping, stability, non-trivial equilibria..

Summary

A direct model coarsely describing warping, endowed with nonlinear constitutive relations, yields field equations for open thin-walled beams. They are numerically integrated using an in-house numerical code, providing non-trivial equilibria and examining their stability. Warping effects on critical loads and natural frequencies for generic cross-sections, affected by constitutive couplings (bending, torsion, warping) are investigated. In addition some methods of validating experiments are described.
