Abstract

The paper presented the influence of fiber orientation on torsional vibrations of thin-walled composite beams with open cross-sections. Equations of motion are derived using the principle of virtual displacements. For a case of arbitrary cross-section and arbitrary stacking sequence differential equations are coupled. A closed-form solution was derived for an I cross-section with arbitrary fiber orientation in laminate.
