5. C modeling#
5.1. Characteristics of modeling#
Modeling: 3D.
The structure is a healthy rectangular parallelepipedic, in which an interface is introduced directly into the command file using the DEFI_FISS_XFEM [U4.82.08] operator. The interface is present at a distance \({L}_{Y}\mathrm{=}\mathrm{1,8}m\) from the top edge of the plate.
5.2. Characteristics of the mesh#
Number of knots: 8644
Number of meshes and types: 6989
including TRIA6: 2600
including TETRA10 :4389
5.3. Tested sizes and results#
The movements resulting from the operator STAT_NON_LINE are post-processed in order to recover the values at the nodes of the crack from the new mesh.
