Abstract
In this paper, we present an experimental investigation and a numerical modelling of thermo-mechanical behaviour of Tournemire argillite. In the first part, the results of triaxial compression tests under two different temperatures are presented in order to show the thermal effect on the mechanical behaviour. In the second part, taking into account the induced thermal effects on shear strength at critical state, a new thermo-elasto-plastic model is proposed for Tournemire argillite. An internal variable is introduced in this model for the purpose of describing thermal effect on elasto-plastic properties. In addition, the post-peak behaviour is considered as a plastic strain softening in the model.
