Finite element analysis of multipass effects of vehicles on soil compaction
… the multipass effect of rubber-tired vehicles on soil compaction. The wheel-soil interaction was modeled as an axisymmetric problem by approximating the elliptical wheelsoil contact area with an equivalent circular area. A hyperbolic stress-strain relationship was used to model the nonlinear …

Stochastic Terrain and Soil Modeling for Off-Road Mobility Studies
… further analyze off-road conditions, stochastic soil properties are incorporated into the terrain topology. Soil models can be developed empirically by measuring soil data at several points, or they can be created by using mathematical relations such as the Bekker's pressure-sinkage equation for …
