| description | This work is a numerical simulation of nonlinear problems of the damage process and fracture of
quasi-brittle materials especially concrete. In this study, we model the macroscopic behavior of concrete
material, taking into account the phenomenon of damage. J. Mazars model whose principle is based on damage
mechanics has been implemented in a finite element program written Fortran 90, it takes into account the
dissymmetry of concrete behavior in tension and in compression, this model takes into account the cracking
tensile and rupture in compression. It is a model that is commonly used for static and pseudo-static systems, but
in this work, it was used in the dynamic case. |
