In this chapter, the elastoplastic framework for the volumetric behavior of soils developed in Chapters 8 and 9 is extended to account for the case of expansive soils. The hydraulic behavior of the soil is simulated using the porous-solid model developed in Chapter 4. The result is an elastoplastic framework where the value and sign of the expansion index depend on the density of the soil as well as the state of stresses and the direction of the increment of the effective stress with respect to the yield surfaces in the plane of effective mean stress against suction. Experimental and numerical comparisons show the ability of the model to simulate the behavior of expansive soils under different stress paths.
