Interclay II is a benchmark exercise involving the numerical modelling of the rheology of clays. Its broad objectives are to improve confidence in long-term predictions of the geomechanical behaviour of clay in situations relevant to the underground disposal of radioactive waste. The project is organised into three distinct phases: the verification of the computer codes, the progression towards validation using well-controlled laboratory tests and the modelling of in situ behaviour. This document reports on the work of stages 2 and 3. In stage 2, two benchmark problems based on laboratory experiments on kaolin clay and Boom clay are modelled and the participants' results are compared. Reasonable agreement is obtained for predictions of temperature and response to thermal loading, but pore pressures and mechanical response vary between participants. In stage 3, the ATLAS test at SCK/CEN's underground research facility at Mol in Belgium are modelled. The analysis results show wide differences between participants for the initial conditions, but the thermal response is reasonably consistent.
