摘要：

Free vibrations of non-symmetrically laminated cross-ply composite beams based on Timoshenko type equations are studied. The effect of coupled longitudinal and transversal displacements, shear deformation and rotary inertia are included in the analysis. Natural frequencies and vibrational modes of laminated beams with different boundary conditions are obtained. Numerical results are presented in order to demonstrate the importance of the coupling effects, shear deformations and rotary inertia in the dynamic analysis of composite beams.
