v6.01.120 SSNA120 — Notched axisymmetric test tube (AE) with joint and interface elements

Summary:

Modeling A makes it possible to ensure the non-regression of a Code_Aster functionality in fracture mechanics and to compare it with a local approach (Rousselier). The functionality tested is the cohesive law for ductile rupture: CZM_TRA_MIX [R7.02.11].

A notched axisymmetric specimen is subjected to traction. The evolution of the force and of the diametral contraction during the propagation of the ductile rupture is calculated. The modeling of the test piece is carried out with elements \(\mathrm{2D}\) (QUA8).

In addition, B modeling makes it possible to validate joint elements in axis (AXIS_JOINT) with the CZM_LIN_REG law.
