Abstract EN
In this paper, some analytical results via extended Galerkin method on free vibration characteristics of an anisotropic composite beam, which is modeled as a nonuniform thin-walled structure with a chordwise asymmetric closed cross-section and corrected the warping functions, are newly presented.
For this study, nonclassical parameters such as warping restraint, transverse shear flexibility, and structural couplings induced by two special configurations, such as circumferentially uniform stiffness (CUS) and circumferentially asymmetric stiffness (CAS), are incorporated.
And also, design parameters of the beam associated with preset angles, pretwist angles, taper ratios, and section ratios are additionally investigated.
The results of this study could play an important role in more efficient designs of composite thin-walled beams.
