Dual-phase-lag heat conduction with microtemperatures
Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (2021-12)
Article
Accés obertIn this paper, we propose a system of equations governing the dual-phase-lag heat conduction with microtemperatures. Several conditions on the coefficients are imposed so that the energy of the system is positive definite ... -
Dual-phase-lag one-dimensional thermo-porous-elasticity with microtemperatures
Liu, Zhuangyi; Quintanilla de Latorre, Ramón (2021-09)
Article
Accés obertThis paper is devoted to studying the linear system of partial differential equations modelling a one-dimensional thermo-porous-elastic problem with microtemperatures in the context of the dual-phase-lag heat conduction. ... -
Energy decay rate of a mixed type II and type III thermoelastic system
Liu, Zhuangyi; Quintanilla de Latorre, Ramón (2010-11-01)
Article
Accés restringit per política de l'editorialIn this paper, we study the energy decay rate for a mixed type II and type III thermoelastic system. The system consist of a wave equation and a heat equation of type II in another part of the domain, coupled in certain ... -
On the phase-lag with equation with spatial dependent lags
Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (2017-11-01)
Article
Accés obertIn 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 the regularity and stability of the dual-phase-lag equation
Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (Elsevier, 2020-02)
Article
Accés obertIn this note we consider the following linear partial different equation which is usually seen as an approximation to the dual-phase-lag heat equation proposed by Tzou. $$ \dot {T}+\tau_q \ddot {T}+\frac{\tau_{q}^{2}}{ ... -
On the regularity and stability of three-phase-lag thermoelastic plate
Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (2022)
Article
Accés obertIn 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 time decay of solutions for non-simple elasticity with voids
Liu, Zhuangyi; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (Wiley-VCH, 2016-07-01)
Article
Accés obertIn this work we consider the non-simple theory of elastic material with voids and we investigate how the coupling of these two aspects of the material affects the behavior of the solutions. We analyze only two kind of ... -
Time decay in dual-phase-lag thermoelasticity: critical case
Liu, Zhuangyi; Quintanilla de Latorre, Ramón (2018-01-01)
Article
Accés obertThis 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 ... -
Two singular problems of dual-phase-lag thermo-porous-elasticity with microtemperatures
Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Summers, M. (2023-06)
Article
Accés restringit per política de l'editorialIn a recent paper the authors studied a generic problem determined by the onedimensional porous-thermoelasticity with microtemperatures in the context of the dual-phase-lag theory. Energy decay rates for that system were ...
