Based on the first-ordershear deformation beam theory, the governing equations are derived from the Lagrange’s equations. Appropriate trigonometric series functions are selected to satisfythe end conditions of the beam. Navier-type solution is used to obtain natural frequencies. Natural frequencies are calculated for different end conditions and laminastacking. It was seen that the slenderness, E11/E22 and fiber angle have a significanteffect on natural frequency. The results of the study are quite compatible with theliterature.eninfo:eu-repo/semantics/openAccessUse of trigonometric series functions in free vibration analysis of laminated composite beamsArticle62616710.20528/cjsmec.2020.02.002372211
