Abstract
A method for tire rolling simulation on sand comprises the steps of modeling a tire using finite elements to build a tire model, modeling a sandy road using finite volumes to build a sandy road model which can exhibit elastoplasticity with both elastic and plastic properties, and executing a numerical simulation in which the tire model is made to roll on the sandy road model in a predetermined condition.
