The practical calculation of the effective elastic tensor with 2D and 3D FEM is detailed. An extension to thermoelasticity is described. Finally, referenc

In contrast to the case of thermoelasticity where the thermal problem has only an effect on the elastic problem and not the opposite, here both problems depend on the solution of each other. After presenting the localization problem defined over the RVE, the different effective operators a

In that situation, the fluid cannot flow but induces a pressure on the solid matrix which affects the mechanical response of the solid. The overall behavior is then called “

More precisely, lack of scale separation occurs when the wavelength associated with the strain and stress fields at the
