4. B modeling#
4.1. Characteristics of modeling#
The simple method of operator PROPA_FISS is used to propagate the crack. The calculation of the propagation (updating of the level sets) is done directly on the mesh of the structure, i.e. no auxiliary grid is used.
4.2. Characteristics of the mesh#
The mesh is the same as that of modeling A.
4.3. Tested sizes and results#
First of all, we test the number of pieces that make up the bottom of the crack at each propagation step:
No propagation |
Reference type |
Reference value |
1 |
“ANALYTIQUE” |
4 |
2 |
“ANALYTIQUE” |
1 |
The position of the bottom of the crack is also tested at each propagation step, which can be done by verifying the maximum value of the y coordinate of the bottom points:
No propagation |
Reference type |
Reference value |
1 |
“ANALYTIQUE” |
16.0 |
