Numerical model of free swelling processes in compacted MX-80 bentonites

This work proposes a formulation to simulate the swelling of compacted bentonites, focusing the analysis on the modelling of the increase of macrostructural void ratio generated by the destructuration of the microstructure under low confinement conditions. First, its formulation is described, highli...
