Resum
In this paper, two new state variables are included in a conventional elastoplastic model, Modified Cam-clay, to incorporate the influence of pore size distribution changes in the mechanical behavior of unsaturated soils. The first state variable allows capturing the influence of large pore changes in the mechanical behavior, and is controlled by an evolution law that incorporates plastic volumetric strain. The second state variable is added to reproduce suction effects and the evolution of this...
