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 existence and numerical approximation in phase-lag thermoelasticity with two temperatures
(2022-04)
Article.
Accés obert
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 ...

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 ...
Hölder stability in type III thermoelastodynamics
(2014-10)
Article.
Accés obert
Article.
Accés obert
This note is concerned with the linear (and linearized) Type III thermoelastodynamic theory proposed by Green and Naghdi. We here assume that the mass density is positive and the thermal conductivity tensor is positive ...
Viscoelastic materials with a double porosity structure
(2019-02)
Article.
Accés obert
Article.
Accés obert
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 ...
On the regularity and stability of three-phase-lag thermoelastic plate
(2022)
Article.
Accés obert
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 ...
Lord–Shulman thermoelasticity with microtemperatures
(2021-10)
Article.
Accés obert
Article.
Accés obert
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 the theory of chiral plates and associated system of Timoshenko–Ehrenfest type
(2021-09)
Article.
Accés obert
Article.
Accés obert
The chiral effects cannot be described by means of the classical theory of elasticity. In this paper we study the thermoelastic deformation of chiral plates in the context of the strain gradient theory of thermoelasticity. ...
Numerical resolution of an exact heat conduction model with a delay term
(2019-02)
Article.
Accés obert
Article.
Accés obert
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 ...
Analysis of a thermoelastic problem of type III
(2020-06)
Article.
Accés obert
Article.
Accés obert
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 ...
