v6.03.122 SSNP122 - Traction. Rousselier model in local and non-local versions

Summary:

This quasistatic test consists in applying a tensile load to a bar. Two versions of the Rousselier model are used with the kinematics of the large Simo and Miehe deformations: the local version and the non-local version (model with a gradient of internal variables). For a traction test, the gradient terms are not activated: we therefore find the results of the local version, at least as long as the solution of the local version remains homogeneous (no localization step).

The bar is modelled by a quadrangular element (QUAD8) in plane deformation.

The results obtained are non-regression results. Both models give identical results as long as the local version solution does not localize. The gradient model solution remains homogeneous throughout the loading path.
