Free Vibration Analysis of Laminated Composite Beams using Finite Element Method

Abstract

First order shear deformation (FSDT) theory for laminated composite beams is used to study free vibration of laminated composite beams, and finite element method (FEM) is employed to obtain numerical solution of the governing differential equations. Free vibration analysis of laminated beams with rectangular cross – section for various combinations of end conditions is studied. To verify the accuracy of the present method, the frequency parameters are evaluated and compared with previous work available in the literature. The good agreement with other available data demonstrates the capability and reliability of the finite element method and the adopted beam model used.
