v1.01.314 ZZZZ314 — Computational validation of DEFI_FOND_FISS

Summary:

The aim of this test is to validate operator DEFI_FOND_FISS in an elementary way through six models, each comprising a meshed crack in a glued configuration (CONFIG_INIT =” COLLEE “). This test does not necessarily have a physical meaning, it is essentially a computer test.

The test case consists in testing the vectors from the local base to the crack bottom according to different DEFI_FOND_FISS configurations.

Case of a rectilinear crack bottom:

Modeling A:

• \(\mathrm{2D}\) mesh.

Modeling B:

• Symmetric \(\mathrm{2D}\) mesh.

C modeling:

• \(\mathrm{3D}\) mesh

D modeling:

• Symmetric \(\mathrm{3D}\) mesh.

Case of a curved crack bottom:

E modeling:

• Model \(\mathrm{3D}\) with a quarter-circle background, from the sslv134b test case.

F modeling:

• Modeling \(\mathrm{3D}\) with symmetry and a closed circular background, from the sslv134a test case.
