Sound absorption by clamped poroelastic plates.
Measurements and predictions have been made of the absorption coefficient and the surface acoustic impedance of poroelastic plates clamped in a large impedance tube and separated from the rigid termination by an air gap. The measured and predicted absorption coefficient and surface impedance spectra exhibit low frequency peaks. The peak frequencies observed in the absorption coefficient are clo...
متن کاملEdge Vibrations in Composite Laminated Sandwich Plates by Using a Higher Order Displacement Based Theory
A higher order displacement based formulation has been developed to investigate the plane strain edge vibrations or end modes in composite laminated sandwich plates. The formulation has been applied as an illustration, to the laminated sandwich plates made up of transversely isotropic laminae with the axes of symmetry lying in the plane of the lamina and core in-between. The results for isotrop...
متن کاملNonlinear vibrations of thin hyperelastic plates
Static deflection as well as free and forced nonlinear vibration of thin square plates made of hyperelastic materials are investigated. Two types of materials, namely rubber and soft biological tissues, are considered. The involved physical nonlinearities are described through the Neo-Hookean, Mooney-Rivlin, and Ogden hyperelastic laws; geometrical nonlinearities are modeled by the Novozhilov n...

Study of Torsional Vibrations of Composite Poroelastic Spherical Shell-Biot’s Extension Theory
Torsional vibrations of composite poroelastic dissipative spherical shell are investigated in the framework of Biot’s extension theory.Here composite poroelastic spherical shell consists of two spherical shells, one is placed on other, and both are made of different poroelastic materials. Consideration of the stress-free boundaries of outer surface and the perfect bonding between two shells lea...
