L'objectiu principal del grup de recerca és l'estudi dels problemes termomecànics que poden ser modelats mitjançant equacions en derivades parcials. Aquest fet ha de ser entès en sentit ampli ja que els problemes tèrmics o, fins i tot, altres tipus de problemes amb valors inicials i a la frontera també són d'interès per al nostre grup.

The main aim of the research group is to study thermomechanical problems that can be modelled in terms of partial differential equations. The group?s field of interest is broad, however, and includes not only thermal problems but also other subjects that can be modelled in terms of initial and boundary value problems.

  • Some remarks on the fast spatial growth/decay in exterior regions 

    Quintanilla de Latorre, Ramón (2019-05-10)
    Article
    Restricted access - publisher's policy
    In this paper we investigate the spatial behavior of the solutions to several partial differential equations/systems for exterior or cone-like regions. Under certain conditions for the equations we prove that the growth/decay ...
  • On the uniqueness and analyticity in viscoelasticity with double porosity 

    Bazarra, Noelia; Fernández, José Ramón; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-04-01)
    Article
    Open Access
    In this paper we analyze the system of equations that models the behaviour of materials with a double porous structure. We introduce dissipation mechanisms in both structures. We show existence, uniqueness and analyticity ...
  • Decay rates of Saint-Venant type for functionally graded heat-conducting materials 

    Leseduarte Milán, María Carme; Quintanilla de Latorre, Ramón (2019-06)
    Article
    Restricted access - publisher's policy
    This paper investigates decay rates for the spatial behaviour of solutions for functionally graded heat-conducting materials. From a mathematical point of view, we obtain a new inequality of Poincarétype. This new result ...
  • Exponential decay in one-dimensional type III thermoelasticity with voids 

    Miranville, Alain; Quintanilla de Latorre, Ramón (Elsevier, 2019-08)
    Article
    Restricted access - publisher's policy
    In this paper we consider the one-dimensional type III thermoelastic theory with voids. We prove that generically we have exponential stability of the solutions. This is a striking fact if one compares it with the behavior ...
  • On quasi-static approximations in linear thermoelastodynamics 

    Knops, Robin J.; Quintanilla de Latorre, Ramón (2018)
    Article
    Restricted access - publisher's policy
    The validity of the coupled and uncoupled quasi-static approximations is considered for the initial boundary value problem of linear thermoelasticity subject to homoge-neous Dirichlet boundary conditions, and for solutions ...
  • Numerical analysis of a thermoelastic problem with dual-phase-lag heat conduction 

    Bazarra, Noelia; Campo, Marco; Fernández, José Ramón; Quintanilla de Latorre, Ramón (2019-06)
    Article
    Restricted access - publisher's policy
    In this paper we study, from the numerical point of view, a thermoelastic problem with dual-phase-lag heat conduction. The variational formulation is written as a coupled system of hyperbolic linear variational equations. ...
  • Numerical resolution of an exact heat conduction model with a delay term 

    Campo, Marco; Fernández, José Ramón; Quintanilla de Latorre, Ramón (2019-02)
    Article
    Open Access
    In this paper we analyze, from the numerical point of view, a dynamic thermoelastic problem. Here, the so-called exact heat conduction model with a delay term is used to obtain the heat evolution. Thus, the thermomechanical ...

    Restricted access - publisher's policy
    This paper in concerned with the linear theory of materials with memory that possess a double porosity structure. First, the formulation of the initial-boundary-value problem is presented. Then, a uniqueness result is ...
  • Qualitative results for a mixture of Green-Lindsay thermoelastic solids

    We study qualitative properties of the solutions of the system of partial differential equations modeling thermomechanical deformations for mixtures of thermoelastic solids when the theory of Green and Lindsay for the ...

    Bazarra, Noelia; Copetti, Maria; Fernández, José Ramón; Quintanilla de Latorre, Ramón (2019-01-15)
    Article
    Restricted access - publisher's policy
    In this paper we analyse, from the numerical point of view, two dual-phase-lag models appearing in the heat conduction theory. Both models are written as linear partial differential equations of third order in time. The ...
  • Exponential stability in type III thermoelasticity with microtemperatures

    In this paper we consider the type III thermoelastic theory with microtemperatures. We study the time decay of the solutions and we prove that under suitable conditions for the constitutive tensors, the solutions decay ...
  • Some qualitative results for a modification of the Green–Lindsay thermoelasticity

    In this short note we consider a recent modification of the Green–Lindsay thermoelastic theory proposed at Yu et al. (Meccanica 53:2543–2554, 2018). We consider a functional defined on the solutions of the problem. It ...
