v6.03.101 SSNP101 - Traction-shear plate: Lemaître viscoelasticity (D_ PLAN)

Summary:

This nonlinear quasistatic mechanical test consists in loading a square plate under tension-shear load.

We thus validate the relationships of nonlinear viscoelasticity behavior in plane deformations for a non-radial loading.

The modeling \(A\) validates \(\mathrm{2D}\) D_ PLANla Lemaître’s law and the VISC_ENDO_LEMA law, for which the parameters are adjusted so that the damage is zero.

Modeling \(B\) validates the VISC_TAHERI law in \(\mathrm{2D}\) D_ PLAN, in which the parameters are adjusted so that the plasticity and ratchet effects are annihilated

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