Patent 7908915 was granted and assigned to Sumitomo Rubber Industries on March, 2011 by the United States Patent and Trademark Office.
A method for tire rolling simulation on mud comprises the steps of modeling a tire using finite elements to build a tire model, modeling a muddy road using finite volumes to build a muddy road model which can exhibit elastoplasticity property and failure property, and executing a numerical simulation in which the tire model is made to roll on the muddy road model in a predetermined condition.
