WebbIn order to quantify the magnitude of thermal pressurisation, we induced temperature change of ~1 K due to rapid hydrostatic loading (10 MPa / 15 min) followed by a 45 min equilibration period of an undrained sample. Here the thermal pressurisation coefficient increases with an increase in effective pressure.

WebbThen, in the numerical implementation, we introduce a sequential implicit method for thermo-poromechanics in multiple porosity systems. Specifically, we extend the fixed-stress sequential Webbin general. In addition, the new poromechanics is formulated to include thermo-mechanical couplings in a double porosity medium (micro- and macro-pores), which contributes to the originality of this work since most existing poromechanics under adsorption are limited to isothermal formulations for single porosity media.
