ESDU 73011
Damping in acoustically excited structures.
Abstract:
ESDU 73011 presents the results of over 500 tests to obtain damping ratio for flat skin-stringer panels with and without viscoelastic jointing compound, for curved skin-stringer panels with viscoelastic jointing compound, for curved and flat integrally-machined skin-stringer panels, and for honeycomb structures. The data are presented as a function of frequency so that the user can readily estimate a damping ratio appropriate to the construction used. Methods of increasing damping are discussed.Indexed under:

- Flat Panels in General
- Flat Sandwich Panels (Cores of Negligible Flexural Stiffness)
- Integrally-Machined Panels
