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 [R7.02.11].

A Compact Tension specimen (\(\mathit{CT}\)) 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 \(\mathrm{2D}\) (QUA8) or elements \(\mathrm{3D}\) (HEXA20).
