✦ Synopsis

Abstraet--A solution procedure for thin-walled laminated composite beams is presented. Two configurations are considered, producing extension-twist and bending-twist coupling, respectively. The influence of coupling on the characteristic equations for free vibration is isolated. It is shown that the characteristic determinant for extension-twist coupling can be expressed as the product of the two decoupled ones. For the ease of bending-twist coupling, a simple-quasi<leeoupled procedure is developed. This model is shown to provide accurate predictions for natural frequencies of practical interest for slender, laminated composite box beams.

The purpose of this paper is to analyze triply coupled vibrations of thin-walled beams with arbitrary open cross-section. Starting from the Vlasov's theory, the governing differential equations for coupled bending and torsional vibrations were performed using the principle of virtual displacements.
