Viscoelastic solids of exponential type. II. Free energies, stability and attractors. Meccanica 39 (2004), no. 6, 547--561.

Summary: "The asymptotic behavior for solutions of the semilinear motion equation of a linear viscoelastic solid of exponential type is studied and the existence of a global attractor is proved. These results are obtained by means of a suitable class of quadratic free energies defined on the minimal state space and making use of semigroup techniques.
