3. Modeling A#
3.1. Characteristics of modeling#
Elasto-plastic calculation on a plane stress model (C_ PLAN). A mesh adaptation is carried out at each time step, followed by a projection and balancing phase. For adaptation, software HOMARD is provided with a very fine description of the geometry of the hole in order to properly follow its outline. Otherwise, concentrations of non-physical stresses appear.
3.2. Characteristics of the mesh#
An initial mesh that includes 91 TRIA6 and 210 nodes is used.

3.3. Tested sizes and results#
We test the value of the stress components at the end of loading:
