B modeling
==============


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).


Characteristics of the mesh
----------------------------

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