Coupled Analysis of Chemo‐Mechanical Processes
A proper understanding of coupled chemo‐mechanical processes often requires the performance of coupled analysis capable of representing the problem in a realistic manner. In this paper, a formulation is presented that combines a thermo‐hydro‐mechanical (THM) approach with the equations of reactive transport in a fully coupled manner. To demonstrate the capability of the formulation and the associated computer code, an example of its application is presented concerning the modelling of a laboratory test in which a specimen of compacted swelling clay is subjected to simultaneous heating and hydration; a situation typical of barriers engineered to isolate high level radioactive waste. In addition, a chemomechanical model accounting for cation exchange effects is briefly introduced. Its performance, coupled to the THMC formulation, is illustrated through the modelling of an oedometer in which the chemical boundary conditions are varied.
