    • On a Caginalp phase-field system with two temperatures and memory 

      Conti, Monica; Gatti, Stefania; Miranville, Alain; Quintanilla de Latorre, Ramón (2017-06)
      Article
      Accés obert
      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 ...

    • On the Caginalp phase-field systems with two temperatures and the Maxwell–Cattaneo law 

      Miranville, Alain; Quintanilla de Latorre, Ramón (2016-10-31)
      Article
      Accés obert
      Our aim in this paper is to study generalizations of the nonconserved and conserved Caginalp phase-¿eld systems based on the Maxwell–Cattaneo law with two temperatures for heat conduction. In particular, we obtain ...

    • On the spatial behavior in two-temperature generalized thermoelastic theories 

      Miranville, Alain; Quintanilla de Latorre, Ramón (2017-10-01)
      Article
      Accés obert
      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 stability in phase-lag heat conduction with two temperatures 

      Magaña Nieto, Antonio; Miranville, Alain; Quintanilla de Latorre, Ramón (2018-06-15)
      Article
      Accés obert
      We investigate the well-posedness and the stability of the solutions for several Taylor approximations of the phase-lag two-temperature equations.We give conditions on the parameters which guarantee the existence and ...

    • On the time decay in phase-lag thermoelasticity with two temperatures 

      Magaña Nieto, Antonio; Miranville, Alain; Quintanilla de Latorre, Ramón (AMER INST MATHEMATICAL SCIENCES-AIMS, 2019-09-12)
      Article
      Accés obert
      The aim of this paper is to study the time decay of the solutions for two models of the one-dimensional phase-lag thermoelasticity with two temperatures. The first one is obtained when the heat flux vector and the inductive ...

    • Parabolic phase-lag heat conduction theories revisited 

      Miranville, Alain; Quintanilla de Latorre, Ramón (Elsevier, 2022-11)
      Article
      Accés restringit per política de l'editorial
      In this note we show that, under certain conditions on the coe cients, the solutions of the parabolic phase-lag heat conduction models are determined by an analytic semigroup for which the inner product determines the ...

    • Some generalizations of the Caginalp phase-field system 

      Quintanilla de Latorre, Ramón; Miranville, Alain (Taylor and Francis, 2009-06)
      Article
      Accés restringit per política de l'editorial
      Our aim in this article is to study generalizations of the Caginalp phasefield system based on a thermomechanical theory of deformable continua proposed by Green and Naghdi. In particular, we obtain well-posedness results ...

    • Spatial decay for several phase-field models 

      Miranville, Alain; Quintanilla de Latorre, Ramón (2013-10)
      Article
      Accés restringit per política de l'editorial
      In this paper, we study the spatial behavior of three phase-field models. First, we consider the Cahn-Hilliard equation and we obtain the exponential decay of solutions under suitable assumptions on the data. Then, for ...
