A generalization of the Timoshenko beam model is presented which accounts for the influence of the shear strains, due to non uniform bending and torsion, on the flexural-torsional vibrations of thin-walled cores with open or closed cross-section. Moreover, a discrete model is derived and two applications are developed concerning torsional and coupled vibrations of open profiles.

Abstract
A generalization of the Timoshenko beam model is presented which accounts for the influence of the shear strains, due to non uniform bending and torsion, on the flexural-torsional vibrations of thin-walled cores with open or closed cross-section. Moreover, a discrete model is derived and two applications are developed concerning torsional and coupled vibrations of open profiles.File in questo prodotto:
