- Abstract
- The aim of this work is the study of general properties of phenomenological and state coefficients in a
thermomechanical model for viscoanelastic media proposed by one of us (VC), in which cross-effect
between viscous and inelastic flow is neglected. In particular, after the specification of the low and high
frequencies region, under physical considerations characterized by limiting the values of some functions
connected to mechanical phenomena, generally valid behaviour for phenomenological and state
coefficients as function of the frequency are deduced. It has been possible, from the entropy production,
to determine some characteristics of the coefficients as function of frequency in order that this principle
is satisfied. The application of the so obtained results to a polymeric material as PolyIsobutilene in these
regions in which, in a first approximation, the medium shows a linear behaviour, confirms our
deductions. (literal)
