摘要：
Free vibration of symmetrically laminated composite beams is studied based on Timoshenko type equations. Shear deformation and rotary inertia are included in the analysis, but with the term representing the joint action of these effects omitted in the Timoshenko equations. Detailed analytical analysis is performed for the natural frequencies of laminated beams with different boundary conditions at their ends, with numerical examples being calculated for a hinged-hinged beam.
