Kurzfassung englisch:
Based on a review of several existing models for the elastic response of geomaterials, a new nonlinear elastic law is suggested. A fully implicit return mapping algorithm for non-associative elastoplastic models of such materials is presented within the regime of large strains. This algoithm is formulated in the principal axes. Algorithmic tangent moduli are derived. A modified critical state model in comjunction with the new nonlinear elastic laws is implemented into the general purpose finite element software MARC, using the proposed algorithm. Furthermore, the tire-sand interaction is numerically simulated, employing the modified model and the algorithm.

Keywords: Finite Element, tire, Large Strain, Plasticity, Sand
