Relaxation strength and distribution function of an internal friction peak

A procedure based on the mechanical properties of a modified anelastic element (MAE) has already been developed to get a functional dependence of the real and imaginary components of the dynamical modulus or compliance. The MAE is essentially a standard anelastic element except for its characteristi...

description A procedure based on the mechanical properties of a modified anelastic element (MAE) has already been developed to get a functional dependence of the real and imaginary components of the dynamical modulus or compliance. The MAE is essentially a standard anelastic element except for its characteristic time, which depends on the frequency. The analysis of this dependence provides an analytical description of not only the dynamical properties but also the distribution function. In this work 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 proposed in the literature. © 1994.
