3. Modeling A

3.1. Characteristics of modeling

The mesh is composed of a single QUAD4 mesh modelled in DKT.

In modeling, we force a single iteration in command STAT_NON_LINEafin to compare with the results of CALCUL. The modeling is under the linear elastic behavior relationship with DEFORMATION = “PETIT”, as well as DEFORMATION = “GROT_GDEP”.

3.2. Comparisons and results

We test the difference between the stress field and the vector of nodal forces calculated by STAT_NON_LINE and those calculated by the CALCUL command.
