      Liu, Zhuangyi; Quintanilla de Latorre, Ramón (2010-11-01)
      Article
      Restricted access - publisher's policy
      In 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
      Open Access
      In 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 ...

      Liu, Zhuangyi; Quintanilla de Latorre, Ramón; Wang, Yang (Elsevier, 2020-02)
      Article
      Open Access
      In 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}}{ ...

      Article
      Restricted access - publisher's policy
      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 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
      Open Access
      In 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 ...

      Article
      Open Access
      This 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 ...
