5. C modeling#

5.1. Characteristics of modeling#

The upwind method of operator PROPA_FISS is used to propagate the crack. An auxiliary grid is used.

5.2. Characteristics of the mesh#

The mesh is the same as that of modeling A.

The auxiliary grid is composed of 2800 elements of type HEXA8 of size \(1.5\times 1.5\times 2\mathit{mm}\). The grid extends inside the holes.

5.3. 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

“ANALYTIQUE”

16.0
