Free Vibration Analysis of Moderate Thickness in Orthotropic Laminated Composite Plate Using FE Method

Alok Kumar, Jyoti Vimal


This study presents the free vibration analysis of a composite laminated plate with respect to various parameters. Effect of orientation on a plate, effect of boundary conditions, effect of thickness to width ratio, effect of changing the number of ply on a plate and the effect of young’s modulus ratio are presented in this study. Classical boundary conditions are used to perform all the studies. Free vibration analysis of plate is performed on ANSYS APDL, by using finite element method. All the responses are verified by the available literature. Convergence and comparison have been done and results are in good agreement with the presented literature. This study state that the parameters which are discussed above have an important role in free vibration or manufacturing of the orthotropic composite laminated plate.
