4. B modeling

4.1. Characteristics of modeling

Same form of mesh as before, but modification of the coordinates of the middle nodes of the edges touching the bottom of the crack, to move them to a quarter of these edges (Barsoum method).

This modification of the coordinates of the nodes is carried out by a procedure GIBI accessible in the mesh data file (SSLP313B .datg).

4.2. Characteristics of the mesh

The mesh consists of 14888 nodes and 6674 elements, including 1392 QUAD8 elements and 5282 TRIA6 elements.
