The results obtained in quadratic without friction with the continuous formulation are in very good agreement with the analytical solution regardless of how the pressure is raised.

It should be noted that the oscillations have almost disappeared compared to modeling A with linear elements. For this purpose, a numerical integration of Gaussian contact terms was used (INTEGRATION =” GAUSS “). The extrapolated master/slave pressures were obtained with the CALC_PRESSION command.
