Abstract:
The mechanical damping behaviour of both metals and polymers is analysed within the theory of the tangent distribution function and its equivalent form, the integrated distribution, which have been recently introduced in the literature. The procedure developed is applied to experimental data on the Zener relaxation in Ag-24at.% Zn, as a function of temperature, for different excitation frequencies. This relaxation process shows a behaviour of the Debye type, and the results obtained are compared with values reported previously. Finally, the method is applied to internal-friction peaks reported in amorphous polyvinyl chloride, for temperatures near the glass transition. A non-singular tangent distribution function is observed in the transition process, together with a temperature dependence of the activation enthalpy, which is discussed in terms of critical phenomena. © 1994 Taylor & Francis Group, LLC.
