4. B modeling#

4.1. Characteristics of modeling#

Method GEOMETRIQUE is used by PROPA_FISS to update the crack position.

4.2. Characteristics of the mesh#

The same mesh as that used for modeling A. is used.

4.3. Tested sizes and results#

We test the values of \({K}_{I}\) at each propagation step.

The mechanical residual error indicator “ERME_ELEM” is also tested on the last propagation step (in non-regression only) in order to validate the use of this indicator on 2D models with rotations.
