Abstract

The vibration of the plates that are made of isotropic and homogeneous materials has been an important subject in the study of noise control, in the aeronautical industry, in the study of fluid-solid interactions and in building construction. It is aimed to investigate the vibrational and acoustical parameters of thin composite plates that are made of fibreglass. A thin, baffled plate of dimension a x b and uniform thickness h, excited by an uniform force density is considered. Vibroacoustical properties of thin clamped composite plate have been reported. The deflection of composite plate has been predicted at different locations on the plate using the classical theory of plate vibration while computational simulations have been carried out to determine deformations of the plate in 3D for different frequency ranges for two boundary conditions.
