Internal friction of a linear viscoelastic solid with a distribution of relaxation times
The dynamical response of a linear viscoelastic solid, when a distribution of relaxation or retardation times is present, is studied in detail. It is shown how the internal friction or loss tangent can be expressed in terms of the expression for a standard anelastic solid, using a distribution which...

Matteo, C.L. distribution of relaxation times dynamical response internal friction Snoek relaxation viscoelastic solid The dynamical response of a linear viscoelastic solid, when a distribution of relaxation or retardation times is present, is studied in detail. It is shown how the internal friction or loss tangent can be expressed in terms of the expression for a standard anelastic solid, using a distribution which is related to the original distribution of relaxation or retardation times, introduced into the dynamical moduli or compliances, respectively.
