    • Porous-elastic plates: Fourier versus type III 

      Fernandez Sare, Hugo D.; Quintanilla de Latorre, Ramón (2021-12)
      Article
      Accés obert
      In this paper we investigate the time decay of the solutions for a thermoelastic plate with voids in the cases when the heat conduction is modeled by the Fourier law and when it is modeled by the type III theory (with and ...

    • Decay of quasi-static porous-thermo-elastic waves 

      Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2021-06)
      Article
      Accés obert
      We study the behavior in time of the solutions to several systems of equations for porous-thermo-elastic problems when one of the variables is considered to be quasi-static or, in other words, whose second time derivative ...

    • On the instability, nonexistence and spatial behaviour of the one-dimensional response of a new class of elastic bodies 

      Quintanilla de Latorre, Ramón; Rajagopal, Kumbakonam (2021-05-22)
      Article
      Accés obert
      In this note we consider 1D problems within the context of a new class of elastic bodies. Under suitable conditions on the constitutive equations we prove instability and nonexistence of solutions similar to those in place ...

    • On existence and numerical approximation in phase-lag thermoelasticity with two temperatures 

      Campo, Marco; Copetti, Maria; Fernández, Jose R.; Quintanilla de Latorre, Ramón (2022-04)
      Article
      Accés obert
      In this work we study from both variational and numerical points of view a thermoelastic problem which appears in the dual-phase-lag theory with two temperatures. An existence and uniqueness result is proved in the general ...

    • A new approach to MGT-thermoviscoelasticity 

      Conti, Monica; Pata, Vittorino; Pellicer Sabadí, Marta; Quintanilla de Latorre, Ramón (American Institute of Mathematical Sciences, 2021-10)
      Article
      Accés obert
      In this paper we discuss some thermoelastic and thermoviscoelastic models obtained from the Gurtin theory, based on the invariance of the entropy under time reversal. We derive differential systems where the temperature ...

    • Numerical analysis of a dual-phase-lag model with microtemperatures 

      Bazarra, Noelia; Copetti, Maria; Fernández, Jose R.; Quintanilla de Latorre, Ramón (2021-08)
      Article
      Accés obert
      In the last twenty years, the analysis of problems involving dual-phase-lag models has received an increasing attention. In this work, we consider the coupling between one of these models and the microtemperatures effects. ...

    • Uniqueness and exponential instability in a new two-temperature thermoelastic theory 

      Fernández, Jose R.; Quintanilla de Latorre, Ramón (AMER INST MATHEMATICAL SCIENCES-AIMS, 2021-03-15)
      Article
      Accés obert
      IIn this work we consider the temperature-rate dependent two temperatures thermoelastic theory. It has been proposed very recently. We study the case in which the elasticity tensor may not be positive definite. Thus, the ...

    • On the approximate problem for the incremental thermoelasticity 

      Bazarra, Noelia; Fernández, Jose R.; Quintanilla de Latorre, Ramón (2021-02-25)
      Article
      Accés obert
      In this work, we study an approximate problem arising in the incremental thermoelasticity. The existence of a unique solution is proved applying the theory of linear semigroups. The exponential energy decay is also considered. ...

    • On the regularity and stability of three-phase-lag thermoelastic plate 

      Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (2022)
      Article
      Accés obert
      In this paper we consider the following three-phase-lag thermoelastic plate u = ¿ ( u ¿ m ); c( _ + q ) = m (u_ + qu ) + (k + + k _): We obtain analyticity and exponential stability for the ...

    • On the decay of the energy for radial solutions in Moore–Gibson–Thompson thermoelasticity 

      Bazarra, Noelia; Fernández, José Ramón; Quintanilla de Latorre, Ramón (2021-10)
      Article
      Accés obert
      In this paper, we consider the Moore–Gibson–Thompson thermoelastic theory. We restrict our attention to radially symmetric solutions and we prove the exponential decay with respect to the time variable. We demonstrate this ...

    • On the quasi-static approximation in the initial boundary value problem of linearised elastodynamics 

      Knops, Robin J.; Quintanilla de Latorre, Ramón (2021-02)
      Article
      Accés obert
      Continuous data dependence estimates are employed to rigorously derive conditions that validate the quasi-static approximation for the initial homogeneous boundary value problem in the theory of small elastic deformations ...

    • Moore-Gibson-Thompson theory for thermoelastic dielectrics 

      Fernández, José Ramón; Quintanilla de Latorre, Ramón (2021-02)
      Article
      Accés obert
      We consider the system of equations determining the linear thermoelastic deformations of dielectrics within the recently called Moore-Gibson-Thompson (MGT) theory. First, we obtain the system of equations for such a case. ...
