Free vibration of a Timoshenko Hybrid composite beam considering the Rayleigh–Ritz method

In the present research, free vibration analysis of the Hybrid composite beam subjected to clamped-freeboundary condition is investigated. The governing equations of a Timoshenko beam are derived and are solvedconsidering the Rayleigh-Ritz method. It is assumed that the material properties of the Hybrid beam are Kevlar andGlass epoxy. Comparing the present results with other experimental literatures in the special case of Hybrid compositebeams, indicates an excellent accuracy. Then, the effects of slenderness.
