    • openAccess   Dissipative Finite-Element Formulation Applied to Piezoelectric Materials With the Debye Memory 

      Palma Guerrero, Roberto; Pérez Aparicio, J. L.; Taylor, Robert L. IEEE (2018-04)
      This work presents a finite-element study of the Debye memory in piezoelectric devices. The memory dependence is due to the spontaneous polarization of the electric dipoles, and it can be understood as a transient ...

    • openAccess   Elasto-thermoelectric beam formulation for modeling thermoelectric devices 

      Palma Guerrero, Roberto; Moliner, Emma; Pérez Aparicio, J. L. Elsevier (2017-07)
      The present paper provides a dynamic, non-linear and fully coupled Finite Element (FE) formulation based on the Timoshenko beam theory to study elasto-thermoelectric responses in thermoelectric devices. The two main ...

    • openAccess   Elasto-thermoelectric non-linear, fully coupled, and dynamic finite element analysis of pulsed thermoelectrics 

      Pérez Aparicio, J. L.; Palma Guerrero, Roberto; Moreno Navarro, P. Elsevier (2016-08)
      This paper presents a numerical study on the influence of pulsed electric signals applied to the overcooling of thermoelectric devices. To this end, an experimental setup taken from the literature and a commercial cell are ...

    • openAccess   Multiphysics and Thermodynamic Formulations for Equilibrium and Non-equilibrium Interactions: Non-linear Finite Elements Applied to Multi-coupled Active Materials 

      Pérez Aparicio, J. L.; Palma Guerrero, Roberto; Taylor, Robert L. Springer (2015-10)
      Combining several theories this paper presents a general multiphysics framework applied to the study of coupled and active materials, considering mechanical, electric, magnetic and thermal fields. The framework is based ...
