ESDU 92001 presents modulus and loss factor for 27 damping materials in the form of reduced temperature nomograms which allow the effects of frequency and temperature on those properties to be considered simultaneously. The data were supplied by 5 manufacturers@ and their addresses in the UK and US are provided. The information is a necessary input in computational procedures@ described in ESDU 91013@ dealing with the application of layered damping treatments to beam- and plate-like structures. Notes are included on the measurement and reliability of the damping quantities that affect the variability allowances to be made when assessing a damping treatment for a particular application. Factors to be considered when selecting a damping material are discussed. Approximate relationships between the elastic properties of damping materials are given.
