RELAXATION STRENGTH AND DISTRIBUTION FUNCTION OF AN INTERNAL-FRICTIONPEAK

A procedure based on the mechanical properties of a modified anelastic element (MAE) has already been developed to get a functional dependen ce of the real and imaginary components of the dynamical modulus or co mpliance. The MAE is essentially a standard anelastic element except f or its characteristic time, which depends on the frequency. The analys is of this dependence provides an analytical description of not only t he dynamical properties but also the distribution function. In this wo rk it is shown that the procedure can be extended to internal friction peaks, yielding not only the parameters of the distribution function but also the relaxation strength. This procedure is applied to various materials and the results are compared with a previous method propose d in the literature.
