Sound Radiation from Orthotropic Rectangular Plates – Part I: Estimation by Asymptotic Method
| Published By | Publication Date | Number of Pages |
| ESDU | 2011-05 | NA |
ESDU 02009 provides methods for the estimation of averaged
radiation efficiencies of orthotropic, rectangular plates which are
simply supported at all edges and surrounded by an infinite baffle.
Isotropic plates are also included as a special case of orthotropic
plates. The method used is approximate and based on an asymptotic
approach. The background to the subject and the nature of
orthotropic plates are explained. The document applies to plates
made of naturally orthotropic materials, such as wood. It can also
be used with equivalent orthotropic plates, such as ribbed,
corrugated or honeycomb panels. Plates of composite materials, such
as carbon fibres in epoxy, are within the scope of the document. In
order to estimate the sound radiation efficiency the dimensions of
the plate, the density and the bending stiffnesses are required.
Two methods are available for the estimation of radiation
efficiencies. The first method is based on design curves presented
in the document and in the second method computer programs are
used. Each design curve is able to apply for a range of
non-dimensional parameters which influence the radiation
efficiency. Use of the design curves gives results which are
accurate to within 2 dB. The results from the computer programs are
more accurate than the results deduced from the design curves. The
computer programs provide output in one-third or one-sixth octave
bands. Applications are described for wooden and composite plates,
corrugated and ribbed plates and honeycombs. Two appendices are
included. The first gives expressions for bending stiffnesses for
different equivalent orthotropic plates. In the second appendix
methods of deriving the bending stiffnesses of plates of composite
materials are described with examples which apply to a single layer
(Kevlar in epoxy) and to a hybrid sandwich with five layers. Two
computer programs, ESDUpacs A0209 and B0209 are provided with this
Item.
