The procedure applies when<br \/>\nlaminae having the same material properties and orientations of<br \/>\ntheir principal axes of orthotropy are symmetrically disposed about<br \/>\nthe mid-plane of the plate. Beam characteristic functions are used<br \/>\nto define the mode shapes, and the analysis sums the contributions<br \/>\nto energy dissipation from each lamina. The input includes<br \/>\nindividual lamina elastic properties, the calculation of which is<br \/>\ntreated in ESDU 83035, and damping properties. Curves are given to<br \/>\nenable approximate values of damping in longitudinal and transverse<br \/>\nflexure and in longitudinal shear to be estimated for each lamina.<br \/>\nGuidance is given on the effect of various factors on the damping<br \/>\nof fibre-reinforced laminated plates, and a practical worked<br \/>\nexample illustrates the use of the method.
