9. H modeling#
9.1. Characteristics of modeling#
The aim of this modeling is to globally validate the entire propagation procedure with cohesive elements. The method GEOMETRIQUE is therefore used by PROPA_FISS, alternately with the operations DETEC_COHESIF and PROPA_COHESIF, to respectively update the tangent level-set (and therefore the propagation front) and the normal level-set (and therefore the « possible » cracking surface).
9.2. Characteristics of the mesh#
A structured mesh is used, the initial crack being meshed. It has 2032 elements of type PENTA6.
9.3. Tested sizes and results#
Two propagation steps are carried out, then the position of the propagation front is extracted at the end of this operation. The validation consists of a non-regression test on the position of this front. In order to reduce the number of tests, the maximum and minimum coordinates \(Y\) and \(Z\) are tested along the front.
