3. Modeling A

3.1. Characteristics of modeling

Modeling AXIS.

3.2. Characteristics of the mesh

The mesh consists of 1803 knots and 1852 meshes including a TRIA3 mesh for the rigid punch, and 1715 QUAD4 links for the solid (the rest of the meshes being SEG2 meshes for the contact surface).

3.3. Characteristics of behavior

Incremental elastic behavior for the punch (COMPORTEMENT/ELAS).

Elasto-plastic behavior in large deformations with linear isotropic work hardening for the solid (COMPORTEMENT/VMIS_ISOT_LINE/SIMO_MIEHE).

3.4. Contact characteristics

Discreet contact method with active constraints algorithm, MAIT_ESCL and normal MAIT_ESCL pairing.

3.5. Tested quantities and results

3.6. notes

The nodal reaction force is in \(\mathrm{N}/\mathrm{rad}\) since the problem is axisymmetric. The difference in the analytical values of the displacement comes from the fact that the rigid punch is modeled by a material with a Young’s modulus of finite stiffness.
