**v6.03.113** SSNP113 - Rotation of main constraints (law of MAZARS)
============================================================================

**Summary:**

This mechanical test case is inspired by the work of Willam [:ref:`bib1 <bib1>`] and was used in the EDF /R & D benchmark "Three-dimensional models of non-linear behaviors of cracked concrete material" [:ref:`bib2 <bib2>`] to evaluate behavior models dedicated to concrete. It is characterized by a specific loading path that creates a continuous rotation of the main stresses. It is used here to test the implementation of the Mazars model. The validation is carried out by comparison with the results obtained with the code CASTEM2000 at LGCNSN (École Centrale de Nantes).
