Equilibrium Solution for a Layer of Soil Loaded by a Rigid, Perfectly Rough Strip Footing

The model analyze the bearing capacity of the underlying soil under rigid concrete footing loaded with external pressure.
The behavior of soil is simulated using the cam -clay model (modified Drucker–Prager model) with parameters matched to the classical Mohr– Coulomb yield model parameters c and φ.

The model provides necessary resistance during compression to the soil by bounding the yield surface thus it provides an inelastic hardening mechanism to represent plastic compaction. Also, this model control volume dilatancy when the material yields in shear by providing softening as a function of the inelastic volume.
