3. Modeling A#

3.1. Characteristics of modeling#

C_ PLAN modeling with sub-integrated QUAD4 elements stabilized by the assumed strain method.

3.2. Characteristics of the mesh#

Number of knots: 527

Number of meshes: 582

SEG2: 102

QUAD4: 480

3.3. Tested sizes and results#

We test the \(\mathit{SIYY}\) coordinate of the stress tensor at various points along the \(\mathit{IJ}\) path

We test with respect to modeling B (AUTRE_ASTER):

In addition, we test (in non-regression):

  • ERME_ELEM and ERME_ELNO (residual error)

  • The SIXX and SIYY constraint at node B
