8. F modeling#

8.1. Characteristics of modeling#

We use a 3D model_ HHO_121 with HEXA27 elements. The mesh used is an extrusion of the modeling A mesh 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 approximate the hypothesis of plane deformations used in models A and B.

8.2. Characteristics of the mesh#

Number of meshes: 1731

QUAD9: 1052

HEXA27: 480

8.3. Tested sizes and results#

We test the \(\mathrm{SIYY}\) coordinate of the stress tensor at various points along the \(\mathrm{IJ}\) path compared to the B modeling.
