11. 2D results summaries

11.1. Summary

First, it was verified that the behavior of the reference structure (modeling A) could be found in 2D (modeling F). After observing the phenomenon of oscillations in 2D, we tested on 2D cases the two algorithms that make it possible to reduce these oscillations in 3D.

The two algorithms tested in the G and H models give, in 2 dimensions, very similar results, and make it possible to reduce the oscillations introduced by the mesh accordingly.

11.2. Comparison curves

The [Figure 11.2-1] represents the contact pressure curves along the Ox axis for the 3 2D models presented. It should be noted that the curves representing the two algorithms overlap almost entirely. The two algorithms are therefore approximately as efficient as each other in 2D. However, they make it possible to reduce oscillations effectively.

It should be noted that mesh refinement obviously increases the precision of the results obtained.
