3. Modeling A#

3.1. 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”). Linear elements are used.

3.2. Characteristics of the mesh#

The mesh contains 108 elements of type QUAD4 and 14 of type TRIA3.

3.3. Tested sizes and results#

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

3.4. notes#

We used linear research (RECH_LINEAIRE) to achieve convergence.
