4. B modeling

4.1. Characteristics of modeling

The loads and materials are identical to those in modeling \(A\).

Only the model of large deformations changes: here we compare SIMO_MIEHE with a VMIS_ISOT_LINE behavior (simulating elastic behavior, through a high elastic limit) and a UMAT behavior (also elastic) with GDEF_LOG.

4.2. Characteristics of the mesh

The mesh is identical to that of modeling \(A\): 200 elements of type QUAD4.

4.3. Tested sizes and results

Comparison of the results obtained with law SIMO_MIEHE with those obtained with GDEF_LOG.
