3. Model A#
3.1. Characteristics of the mode#
In this model, the crack is meshed (FEM case).
We use the SYME = YES keyword for the crack.
The rmed result has been generated continuously.

3.2. Characteristics of the mesh#
Number of nodes: 317
Number of cells and type: 562 POI1, 24 SEG2, 24, 9, 9 TRIA3, 9, 239 QUAD4, 12 PENTA6, and 180 HEXA8.
3.3. Calculations made#
The POST_J operator is tested against POST_K1 and CALC_G option G.
3.4. Tested sizes#
