In the present contribution, the frictional material soil is considered within the well‐founded framework of the Theory of Porous Media ]1–3[. The model represents a multi‐phase medium consisting of a solid skeleton, a pore‐liquid (here water) and a pore‐gas (here air). Concerning the solid skeleton, a general elasto‐plasticity approach including a soil‐foundation interface is presented. In particular, to describe granular soils like sand, a physically non‐linear soil elasticity law ]4[ is taken into consideration. In the plastic domain, use is made of the single‐surface yield function by Ehlers ]2[, which is extended towards isotropic work‐hardening materials.
