FREE-VIBRATIONS OF NONSYMMETRICAL CROSS-PLY LAMINATED COMPOSITE BEAMS

Free vibrations of non-symmetrically laminated cross-ply composite bea ms based on Timoshenko type equations are studied. The effect of coupl ed longitudinal and transversal displacements, shear deformation and r otary inertia are included in the analysis. Natural frequencies and vi brational 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.
