Thermodynamics of non-local materials: extra fluxes and internal powers
TL;DR: The most usual formulation of the Laws of Thermodynamics turns out to be suitable for local or simple materials, while for non-local systems there are two different ways: either modify this usual formulation by introducing suitable extra fluxes or express the laws of thermodynamics in terms of internal powers directly as mentioned in this paper.

A theory of thermoelasticity with diffusion under Green-Naghdi models
TL;DR: In this paper, the authors used the Green-Naghdi theory of thermomechanics of continua to derive a nonlinear theory of thermoelasticity with diffusion of types II and III, which permits propagation of both thermal and diffusion waves at finite speeds.

Thermodynamics of non-local materials: extra fluxes and internal powers
TL;DR: In this article, the authors propose a general formulation of the Laws of Thermodynamics in terms of internal powers, which is a priori defined on the basis of the constitutive equations and allows to highlight the contribution of the internal powers in the variation of the thermodynamic potentials.

Continuous dependence on modelling for temperature-dependent bidispersive flow
TL;DR: In this article, the authors consider a model for flow in a porous medium which has a double porosity structure, where the usual porosity is called macro porosity, but in addition, they allow for a porosity due to cracks or fissures in the solid skeleton.

Mathematical models for the non-isothermal Johnson–Segalman viscoelasticity in porous media: stability and wave propagation
TL;DR: In this article, a nonlinear model for Johnson-Segalman type polymeric fluids in porous media, accounting for thermal effects of Oldroyd-B type, is presented, which is consistent with the interlacement between thermal and viscoelastic relaxation effects and diffusion phenomena.
