10. H modeling#

10.1. Characteristics of modeling#

We use a 3D model_ HHO_121 with HEXA27 elements. The mesh used is an extrusion of the mesh from modeling \(A\) over a height of \(\mathrm{0,1}m\) with a single element in the thickness. All degrees of freedom are blocked according to \(Z\) in order to get closer to the hypothesis of plane deformations used in the \(A\) and \(B\) models. The behavior is GDEF_LOG.

10.2. Characteristics of the mesh#

Number of meshes: 1731

QUAD9: 1052

HEXA27: 480

10.3. Tested sizes and results#

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