v6.03.005 SSNP05 - Traction-shear plate: Lemaître viscoelasticity

Summary:

This nonlinear quasistatic mechanical test consists in loading a square plate under tension-shear load. We thus validate Lemaître’s nonlinear viscoelasticity behavior relationship (in \(\mathrm{3D}\)) for a non-radial loading. This test is taken from the guide VPCS of the Société Française de Mécanique.

The plate is modelled by a volume element (HEXA8).

The results obtained by*Code_Aster* are very close to the reference solution.
