ResumoThe purpose of this paper is to present a new finite element formulation for the hydro-thermo-mechanical analysis of elasto-plastic multiphase materials based on Porous Media Mechanics. To this end, the ACMEG-T thermo-plastic constitutive model for saturated soils has been implemented in the finite element code COMES-GEO. Validation of the implemented model is made by selected comparison between model simulation and experimental results for different combinations of thermo-hydro-mechanical loading paths. A case of non-isothermal elasto-plastic consolidation is also shown.
