7. F modeling#

This modeling is similar to the D model (mesh TRIA3, topological enrichment), but the load is applied via pressure on the lips of the crack.

Only the horizontal crack is tested.

The results are less accurate than those of the D modeling.

In fact, when pressure is imposed on the lips of the crack, it is necessary to use small crowns.
