10. H modeling: triangles (algorithm version 2)#
10.1. Characteristics of the mesh#
The mesh is identical to that of the G modeling.
10.2. Features tested#
Friction is taken into account and the contact is active from the 1st iteration of active stresses.
The algorithm for restricting the space of Lagrange multipliers is No. 2.
10.3. Tested sizes and results#
The contact pressure value is tested at point \(P\) with coordinates \((\mathrm{10,}17.5)\).

10.4. Comments#
This modeling shows that in 2D, the version 2 algorithm behaves very closely to that of version 1. In fact, apart from the first contact pressures measured on the left side of the mesh, the values observed are identical, and the curves obtained with the two algorithms almost entirely overlap. (see [Figure 11.2-1]).
