In this contribution problems relating to the non-linear interaction between an elastic tire and soft soil are discussed. A basic approach for solving this problem is described, where the friction force is modeled as a function dependent on the lateral displacement of the tire. The sinking of the tire is not accurately modeled – it is approximated by increasing the friction coefficient both linearly and non-linearly. The behavior exhibited using the approaches described is compared with measured behavior from real tests and the potential of the approach is appraised.
