The compaction and stress generation on terrain, were always investigated based on empirical approaches or testing methods for tire/terrain interaction. However, the analysis should be performed for various tires and at different soil strengths. With the increasing capacity of numerical computers and simulation software, finite element modeling of tire/terrain interaction seems a good approach for prediction of effect of change in the parameters. In this study, an elaborated 3D model fully compliant with the geometry of radial tire 115/60R13 is worked up, using commercial code Solidwork Simulation. The hyper-elastic and incompressible rubber as tire main material is analyzed by Moony- Rivlin model. The Drucker-Prager yield criterion is used to model the soil compaction. Results show that the model realistically predicts the laboratory tests outputs of the modeled tire on the soft soil.
