A study is presented of the coupled bending-bending-torsion vibrations of a pre-twisted rotating cantilever beam of fibre-reinforced material. The free vibration and dynamic stability problems are discussed. The transverse shear deformation and rotary inertia are included. The effect of the pre-twisted angle, fibre orientation and rotation are studied. Numerical results have been calculated by using the finite element method, and they show that the effects mentioned above are more complex for orthotropic beams than for isotropic ones.
