3.1. Characteristics of modeling#

2D axi-symmetric modeling

Boundary conditions are modelled by:

On the nodes (N01, N02, N05, N06), DY=0.

The mechanical calculation is carried out with the Von Mises elasto-plastic behavior law with linear isotropic work hardening (keyword “RELATION = VMIS_ISOT_LINE”). Work hardening restoration is activated only on the M1 mesh (keyword POST_INCR = “REST_ECRO”).

3.2. Characteristics of the mesh#

Number of knots:

6

Number of meshes and type:

2 QUAD4

3.3. Tested sizes and results#

We test the non-regression of the values of \(p\) and \({\sigma }_{\mathit{yy}}\) at the nodes N01 and N06 for the moments 89s and 200s.
