Vibration Analysis of Composite Plate at Different Boundary Conditions

Abstract

In this paper a Vibration Analysis of a composite plate is presented at different boundary condition applied on it. Generally plates are subjected to load conditions that cause deflections transverse to the plate. Vibration directly influences the performance and life of engineering structures, and invariably, damping in the structures influenced its vibration behavior. Various types of damping mechanisms have been developed over time to control the undesired vibration of structures. a plate Finite Element formulation and problem modelled in ANSYS platform, are provided with emphasis on the terms related to the stiffness and mass matrices. Then, a set of results are presented to show the applicability of the present problem to various types of plates under free vibration conditions. Subsequently Three ply laminates has been considered and results are compared with isotropic plate
