u2.05.00 Realization of a calculation to predict breakage by cleavage

Summary

This documentation is intended to provide the information needed by a user wishing to simulate a breakage by cleavage using*code_aster*.

The definition of cleavage is initially recalled. We then present in turn the models present in Code_Aster to predict this type of rupture and methodological and implementation advice. The models described here are in turn: Beremin, Bordet, Gp and Le Corre.
