  • Two-temperatures thermo-porous-elasticity with microtemperatures 

    Fernández, Jose R.; Quintanilla de Latorre, Ramón (Elsevier, 2021-01)
    Article
    Restricted access - publisher's policy
    In this note, we study a linear system of partial differential equations modelling a one-dimensional two-temperatures thermo-porous-elastic problem with microtemperatures. A new system of conditions is proposed to guarantee ...

  • An a priori error analysis of a Lord–Shulman poro-thermoelastic problem with microtemperatures 

    Baldonado, Jacobo; Bazarra, Noelia; Fernández, Jose R.; Quintanilla de Latorre, Ramón (2020-07-08)
    Article
    Restricted access - publisher's policy
    In this paper, we deal with the numerical analysis of the Lord–Shulman thermoelastic problem with porosity and microtemperatures. The thermomechanical problem leads to a coupled system composed of linear hyperbolic partial ...

  • Moore-Gibson-Thompson thermoelasticity with two temperatures 

    Quintanilla de Latorre, Ramón (Elsevier, 2020-05)
    Article
    Open Access
    In this note we propose the Moore-Gibson-Thompson heat conduction equation with two temperatures and prove the well posedness and the exponential decay of the solutions under suitable conditions on the constitutive parameters. ...

  • Analysis of a Moore-Gibson-Thompson thermoelastic problem 

    Bazarra, Noelia; Fernández, Jose R.; Quintanilla de Latorre, Ramón (2021-01-15)
    Article
    Restricted access - publisher's policy
    In this work, we numerically consider a thermoelastic problem where the thermal law is modeled using the so-called Moore-Gibson-Thompson equation. This thermomechanical problem is written as a coupled system composed of a ...

  • On the analyticity of the MGT-viscoelastic plate with heat conduction 

    Conti, Monica; Pata, Vittorino; Pellicer, Marta; Quintanilla de Latorre, Ramón (2020-10)
    Article
    Restricted access - publisher's policy
    We consider a viscoelastic plate equation of Moore-Gibson-Thompson type coupled with two different kinds of thermal laws, namely, the usual Fourier one and the heat conduction law of type III. In both cases, the resulting ...

  • Analysis of a thermoelastic problem of type III 

    Bazarra, Noelia; Fernández, Jose R.; Quintanilla de Latorre, Ramón (2020-06)
    Article
    Restricted access - publisher's policy
    This paper investigates several aspects of the linear type III thermoelastic theory. First, we consider the most general system of equations for this theory in the case that the conductivity rate is not definite and we ...

  • Lord–Shulman thermoelasticity with microtemperatures 

    Bazarra, Noelia; Fernández, José Ramón; Quintanilla de Latorre, Ramón (2020-06-06)
    Article
    Restricted access - publisher's policy
    In this paper we consider the Lord–Shulman thermoelastic theory with porosity and microtemperatures. The new aspect we propose here is to introduce a relaxation param- eter in the microtemperatures. Then we obtain an ...

  • On uniqueness and instability for some thermomechanical problems involving the Moore– Gibson–Thompson equation 

    Pellicer, Marta; Quintanilla de Latorre, Ramón (2020-06)
    Article
    Restricted access - publisher's policy
    It is known that in the case that several constitutive tensors fail to be positive definite the system of the ther- moelasticity could become unstable and, in certain cases, ill-posed in the sense of Hadamard. In this ...

  • Exponential decay in one-dimensional Type II/III thermoelasticity with two porosities 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2020-04-26)
    Article
    Restricted access - publisher's policy
    In this paper we consider the theory of thermoelasticity with a double porosity structure in the context of the Green-Naghdi types II and III heat conduction models. For the type II, the problem is given by four hyperbolic ...

  • An a priori error analysis of poro-thermoviscoelastic problems 

    Bazarra, Noelia; Fernández, Jose R.; Quintanilla de Latorre, Ramón (Elsevier, 2020-08-15)
    Article
    Restricted access - publisher's policy
    In this paper, we study, from the numerical point of view, a dynamic one-dimensional problem arising in thermoelasticity and thermoviscoelasticity of types II and III. Porosity is also included into the models. The generic ...

  • Asymptotic behavior of a Cahn-Hilliard/Allen-Cahn system with temperature 

    Miranville, Alain; Quintanilla de Latorre, Ramón; Saoud, Wafa (2020-04)
    Article
    Restricted access - publisher's policy
    The main goal of this paper is to study the asymptotic behavior of a coupled Cahn-Hilliard/Allen-Cahn system with temperature. The work is divided into two parts: In the rst part, the heat equation is based on the usual ...

  • Numerical analysis of a dual-phase-lag model involving two temperatures 

    Bazarra, Noelia; Fernández, José Ramón; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-12-27)
    Article
    Restricted access - publisher's policy
    In this paper, we numerically analyse a phase-lag model with two temperatures which arises in the heat conduction theory. The model is written as a linear partial differential equation of third order in time. The variational ...
