Analysis of anelastic relaxations controlled by a spectrum of relaxation times
Abstract
Anelastic studies, although providing an important method for investigating the mobility of point defects in solids, often were difficult to analyze when a continuous spectra of relaxation times controls the anelastic response. A new method for obtaining accurate estimates of relaxation time spectra by direct analysis (without prior assumptions) of the data using a nonlinear regression method are described. Applications to internal friction and anelastic creep results are described with emphasis upon the internal friction technique.
