A microstructural effective stress definition for compacted active clays

The volumetric deformability of the microstructure of compacted active clays is linked to the water mass exchange with the macrostructural void space. Given that this exchange is determined by the difference in the chemical potential of water in these two structural levels, this work proposes to def...
