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.

  • Time decay in dual-phase-lag thermoelasticity: critical case  

    Liu, Zhuangyi; Quintanilla de Latorre, Ramón (2018-01-01)
    Article
    Accés restringit per política de l'editorial
    This note is devoted to the study of the time decay of the onedimensional dual-phase-lag thermoelasticity. In this theory two delay parameters tq and t¿ are proposed. It is known that the system is exponentially stable if ...
  • On the spatial behavior in two-temperature generalized thermoelastic theories 

    Miranville, Alain; Quintanilla de Latorre, Ramón (2017-10-01)
    Article
    Accés restringit per política de l'editorial
    This paper investigates the spatial behavior of the solutions of two generalized thermoelastic theories with two temperatures. To be more precise, we focus on the Green–Lindsay theory with two temperatures and the Lord–Shulman ...
  • On the viscoelastic mixtures of solids 

    Fernández, Jose R.; Magaña Nieto, Antonio; Masid, Maria; Quintanilla de Latorre, Ramón (2017-07-12)
    Article
    Accés restringit per política de l'editorial
    In this paper we analyze an homogeneous and isotropic mixture of viscoelastic solids. We propose conditions to guarantee the coercivity of the internal energy and also of the dissipation, first in dimension two and later ...
  • Stability for thermoelastic plates with two temperatures 

    Quintanilla de Latorre, Ramón; Racke, Reinhard (2017-12-01)
    Article
    Accés restringit per política de l'editorial
    We investigate the well-posedness, the exponential stability, or the lack thereof, of thermoelastic systems in materials where, in contrast to classical thermoelastic models for Kirchhoff type plates, two temperatures are ...

    Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (2017-11-01)
    Article
    Accés restringit per política de l'editorial
    In this paper we investigate several qualitative properties of the solutions of the dual-phase-lag heat equation and the three-phase-lag heat equation. In the first case we assume that the parameter tTtT depends on the ...
  • On uniqueness and stability for a thermoelastic theory 

    Quintanilla de Latorre, Ramón (2017-06)
    Article
    Accés restringit per política de l'editorial
    In this paper we investigate a thermoelastic theory obtained from the Taylor approximation for the heat flux vector proposed by Choudhuri. This new thermoelastic theory gives rise to interesting mathematical questions. We ...
  • On a Caginalp phase-field system with two temperatures and memory

    Article
    Accés restringit per política de l'editorial
    The Caginalp phase-field system has been proposed in [4] as a simple mathematical model for phase transition phenomena. In this paper, we are concerned with a generalization of this system based on the Gurtin-Pipkin law ...

    Article
    Accés restringit per política de l'editorial
    We study solutions for the one-dimensional problem of the Green-Lindsay and the Lord-Shulman theories with two temperatures. First, existence and uniqueness of weakly regular solutions are obtained. Second, we prove the ...

    Article
    Accés restringit per política de l'editorial
    This article is concerned with the linear theory of chiral Cosserat thermoelas- tic bodies. We investigate the deformation of chiral plates. First, we present the basic equations which govern the deformation of thin plates. ...
