Summary

This paper presents the modelling of a body in rolling contact taking into account:

Three-dimensional finite deformation (Mooney-Rivlin or Yeoh)
Dynamics
Heterogeneities of the material
Friction
Thermomechanical coupling in the contact zone: the material properties do not depend on temperature, but the friction law takes into account the thermal effect.

We consider two numerical approaches:

A classical one, using a Lagrangian formulation for the mechanical and thermal problems.
The steady-state rolling approach (Eulerian approach) for the mechanical problem associated with a Lagrangian approach for the thermal problem.

The last approach has the advantage of using a fine mesh only in the real contact zone which does not change during rolling. The mesh is fixed while the material travels inside with prescribed velocity. The two methods are compared and are applied to the rolling contact of tyres; numerical results are presented.
