**r7.01.08** MAZARS damage model
=============================================

**Summary:**

This documentation presents the MAZARS behavior model that allows to describe the elastic-damaging behavior of concrete. This model is 3D, isotropic and is based on a damage criterion written in deformation and describing traction-compression asymmetry. The initial model does not account for the restoration of stiffness in the event of "reclosing cracks" and does not take into account the possible plastic deformations or viscous effects that may be observed during the deformations of a concrete. The version implemented in Code_Aster takes into account the latest improvements. This reformulation of the Mazars model from the 1980s makes it possible to better describe the behavior of concrete under bi-compression and in pure shear.

Version :math:`\mathrm{1D}` of the model makes it possible to report on the restoration of stiffness in the event of cracks being closed; it is only used with multifibre beams [:ref:`R5.03.09 <R5.03.09>`].
