This paper analyzes the time differential three-phase-lag model of coupled thermoelasticity. The uniqueness and continuous dependence results are established for the solutions of the corresponding initial boundary value problems associated with the model in concern. The key tool of the method is to associate with the basic initial boundary value problem of the model an appropriate auxiliary initial boundary value problem and then to establish an identity of Lagrange type. This last identity is used to analyze the uniqueness of solutions under appropriate mild restrictions assumed upon the constitutive coefficients and upon the delay times. Uniqueness question is also discussed for a set of models of thermoelasticity developed in literature. Further, for the continuous dependence problem an appropriate estimate of the solution is obtained in terms of the given data. This expresses the continuous dependence of solution with respect to the initial data and with respect to the given supply loads, provided some appropriate constitutive assumptions are considered. These results give information upon the well-posedness of the time differential three-phase-lag model of coupled thermoelasticity.

Content available remote Some results on the spatial behaviour in linear porous elasticity
EN
In this paper we study the spatial behaviour for an extended class of isotropic and homogeneous porous materials for which the constitutive coefficients are supposed to satisfy some relaxed positive denniteness conditions. By using some appropriate measures, we are able to establish results describing the spatial behaviour of transient and steady-state solutions in these enlarged classes of porous materials.

Content available remote On some exponential decay estimates for porous elastic cylinders
EN
In this paper we introduce two new cross-sectional measures for studying the spatial behaviour of the solutions in elastostatics of the porous cylinders. This allows us to extend the range of applicability of the estimates describing the Saint-Venant's decay behaviour of enlarged classes of porous materials.
