چكيده فارسي :
In the present research, free vibration analysis of the Hybrid composite beam
subjected to clamped-free boundary condition is investigated. The governing
equations of a Timoshenko beam are derived and are solved considering the
Rayleigh-Ritz method. It is assumed that the material properties of the Hybrid
beam are Kevlar and Glass epoxy. Comparing the present results with other
experimental literatures in the special case of Hybrid composite beams,
indicates an excellent accuracy. Then, the effects of slenderness ratios as well
as stacking sequences of the Hybrid composite beam on fundamental
frequencies are taken into account.
