**v6.03.151** SSNP151 — Compact Tension (CT) test tube in 2D and 3D with the CZM_TRA_MIX law
==============================================================================================

**Summary:**

This nonlinear static mechanics test makes it possible to ensure the non-regression of a *Code_Aster* functionality in fracture mechanics. The functionality tested is the law of ductile rupture: CZM_TRA_MIX [:ref:`R7.02.11 <R7.02.11>`].

A Compact Tension specimen (:math:`\mathit{CT}`) is subjected to traction. The change in force during the propagation of the ductile fracture is calculated.

The modeling of the test piece is carried out with elements :math:`\mathrm{2D}` (QUA8) or elements :math:`\mathrm{3D}` (HEXA20).
