4. B modeling

4.1. Characteristics of modeling

We use a MEMBRANE modeling in large deformations (DEFORMATION =” GROT_GDEP “) with the Saint Venant Kirchhoff law of behavior (RELATION =” ELAS_MEMBRANE_SV”). Quadratic elements are used.

4.2. Characteristics of the mesh

The mesh is the same as for modeling A but in quadratic form. It contains 108 elements of type QUAD8 and 14 of type TRIA6.

4.3. Tested sizes and results

We test the displacement in the center of the disk, in O.

Identification	Reference type	Reference value (\(\mathit{mm}\))	Precision
Point \(O\) - \(\mathit{DZ}\)	“SOURCE_EXTERNE”	2448	2%

4.4. notes

We used linear research (RECH_LINEAIRE) to achieve convergence.
