The symmetry boundary conditions are:
On the stitches DEVANT and DERRIERE : :math:`DX=0`. *On the stitches GAUCHE and DROITE : :math:`DY=0`. *On the mesh BAS *: \(DZ=0\).
3.2. Tested sizes and results#
The solutions are calculated at points NO8 to \(t=1, 2\) and \(t=3\) each corresponding to the times at which the three loads are completed. They are given in terms of deformation \(\varepsilon_{zz}=\varepsilon_v/3\) in v7.31.126-resultats_grandeurs.
The Fig. 3.2 shows the answers obtained.
