3. D modeling#
3.1. Characteristics of modeling#
This modeling is identical to modeling A (and in particular the mesh). The only difference is the resolution method, which is here « PENALISATION », with penalties for contact and friction.

3.2. Tested values: SIGM_ELNO#
The normal pressure forces generated by the contact and friction are tested. These efforts, defined in polar coordinates, are expressed in \(\mathit{Pa}\).
