**v6.03.116** SSNP116 - Creep/crack coupling - Uniaxial traction
=========================================================================

**Summary:**

This validation case is intended to verify the coupling model of Granger creep laws with plasticity/cracking laws. The coupling, initially restricted to a few laws of the non-linear environment of *Code_Aster*, can be extended later to more laws. The parameters of the plasticity/cracking models are chosen in a particular way to model an almost perfect elasto-plastic behavior, and to reduce to a problem presenting a relatively simple analytical solution.

The geometry consists of three linear elements (cubes and prisms in :math:`\mathrm{3D}`, squares and triangles in :math:`\mathrm{2D}`), and three quadratic elements, connected to the previous ones by linear relationships. The models tested here are the 3D models, C_ PLAN, and D_ PLAN.

The load is uniaxial traction in imposed displacement.

The coupling of the Granger creep model with BETON_DOUBLE_DP and VMIS_ISOT_LINE is tested. The analytical solution is available in 3D and C_ PLAN, when there is no change in the water content.

In the 3D and D_ PLAN cases, the solutions obtained are also tested when there is a variation in the water content and in the temperature with activation of the corresponding withdrawals (with opposite sign). These are then non-regression tests.
