Large Deformation Finite Element Analysis of Soil-Tire Interaction Based on the Contact Mechanics Theory of Rolling and/or Sliding Bodies

摘要

This research program is aimed at the development of a soil-tire interaction model based on Contact Mechanics Theory. The model developed obviates the need for a priori knowledge of soil-tire contact properties and instead relies on directly and accurately measurable quantities. Other major research outcomes of this program include: (1) the first complete solution to the frictional contact problem between a granular material and a deformable solid, (2) extension of the Double Shearing theory for dilatant granular flow to three dimensions and (3) the development of a new technique for the micro-mechanical analysis of granular media.
