1. Reference problem

It is a square plate with a \(a\mathrm{=}10.\) side and a \(t\mathrm{=}1\) thickness.

1.1. Material properties

\(E\mathrm{=}1.\)

\(\nu \mathrm{=}0.3\)

1.2. Boundary conditions and loading

The plate is embedded along side \(\mathit{AB}\).

We have 7 load cases for modeling A and 5 load cases for modeling B.

Each load case corresponds to the superposition of 2 loads that cancel each other out.

One of these loads applies to a GROUP_MA or GROUP_NO defined from a geometric criterion in DEFI_GROUP, the other, with the opposite sign, applies to the GROUP_MA or the GROUP_NO defined « in extension » (by hand).

Modeling A uses a « 3D » model in shell DKT.

B modeling uses a « D_ PLAN » model in TRIA3.

The meshes are the same.
