Note s :

Regarding efforts, direct calculation at the nodes leads to discrepancies in several nodes, especially at point F in DSQet on the edge \(\mathrm{ABC}\) en Q4G.

Modeling with COQUE_SOLIDE elements (N modeling) is the only plate modeling that accounts for the pinch effect with a linear constraint in the thickness.
