Abstract
It is well known that viscosity of water-saturated clay is affected by temperature variation as well as strain rate. In addition, the conservation of energy during deformation should be considered since the plastic stress power changes the temperature of soil. In this paper, thermohydro-mechanically coupled finite element method using an elasto-thermo-viscoplastic constitutive model for clay is newly developed. And then, a series of strain localization analysis under undrained plane strain conditions and thermal consolidation mainly due to heatgenerated pore water pressure are simulated by thermo-hydro-mechanically coupled finite element method.
