• The dynamic property and behavior of the soft ground are greatly affected by the constituent grains shape. The consideration of the elastic-plastic property of the soft ground is also important for the multipass calculation of the tire on the soft ground. We developed the efficient interactive model of the tire and the soft ground that were composed of the distributed lumped mass-spring model as the tire, Discrete Element (DE) model as the upper soft ground, and the mass-spring model as the lower soft ground. In the present study, we have improved the previous soft ground model by considering the grains shape and the elastic-plastic property of the soft ground, and have confirmed these effects through several numerical simulations.
