4. B modeling#
4.1. Characteristics of modeling#
The modeling is identical to the modeling A, but in this case we will work with plane deformations (D_ PLAN) and, as already mentioned above, the Poisson coefficients no longer intervene in the solution.
The outer ring defines the master surface.
4.2. Characteristics of the mesh#
Idem modeling A.
4.3. Tested sizes and results#
The contact pressure (LAGS_C) is calculated for the node \(A\) with coordinates \((0.6\mathrm{,0}.0)\), the node that at the initial moment is located farthest to the right of the interface between the two rings.

For a few steps of load, the calculated value is compared to that given by equation 1.5. The accuracy is less than 1%.
4.4. Comments#

Idem modeling A.
