Abstract
The general thermomechanical and mixture theoretical model derived by Jussila [Transport Porous Med 62, 81–107 (2006)] is applied to the fully coupled thermo-hydro-mechanical description of swelling compacted bentonite. The particular form of the free energy of the clay constituent is chosen to take into account non-linear elastic strain and moisture swelling. The model parameters are calibrated by the simulation of various coupled experiments for compacted Almerian bentonite. Numerical implementation is done with the multi-purpose finite element method software ELMER (CSC 2005).
