Hydroplaning, Snow-Tire Interaction, and Mud-Tire Interaction are becoming of increasing interest to Tire industry.  With the availability of High Performance Computing, these analysis can now be routine and included as part of tire workflows.

These interactions are either Fluid-Structure Interaction type (i.e., Hydroplaning), or involve complex material behavior undergoing large permanent deformation in both volumetric and shear (i.e., snow or mud).  The Eulerian framework where the mesh is stationary and the material moves within mesh is more effective than the traditional lagrangian framework for these cases.  Abaqus’ Coupled Eulerian-Lagrangian (CEL) technology can model the contact of the lagrangian tire with the eulerian material (water, snow or mud) in the General Contact framework of Abaqus/Explicit.  A general overview of this capability along with general material models will be presented to demonstrate the application of CEL within Abaqus.
