A number of issues related to the modelling, vibration and stability of anisotropic pretwisted beams rotating at constant angular speed about the longitudinal body-axis "xed in the inertial space are investigated. The analysis is carried out in the framework of a re"ned theory of thin-walled anisotr

This paper presents numerical study about the in#uence of the shear #exibility, due to either bending and warping, on the out-of-plane free vibration of continuous horizontally curved thin-walled beams with both open and closed sections. This study was made by means of a recently developed "nite ele
A three-dimensional, two-field, variational formulation is employed to derive the differential equations governing the dynamics of stretching, shearing, bending and twisting, as well as warping modes of deformations in a spatially curved beam with arbitrary cross-section. Correspondingly, the finite
