5.4. notes#

The results obtained in linear mode with friction with the continuous formulation are in good agreement with the analytical solution when the extrapolated contact pressure on the master surface is recorded.

However, we will note the strong oscillation of the contact pressure when it is measured from the degree of freedom LAGS_C specific to the continuous formulation. The amplitude of the oscillations decreases when the mesh is refined. CALC_PRESSION is used for extrapolated pressures.

The results obtained by the commercial codes Abaqus and MARC in the benchmark also show oscillations for the case with friction.
