v6.01.001 SSNA01 - Infinite cylinder under pressure: Lemaître viscoelasticity

Summary:

This nonlinear quasistatic mechanics test consists in modeling an infinite cylinder subjected to internal pressure depending on time. Lemaître’s nonlinear viscoelasticity behavior relationship is thus validated axisymmetrically, and on a complete mesh. This test is taken from guide VPCS from SFM.

The cylinder is modelled by axisymmetric \(\mathrm{2D}\) elements (QUAD8).

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