Formulation of anisotropic damage in quasi-brittle materials and structures based on discrete element simulation

Quasi-brittle materials, commonly found in civil engineering structures, tend to degrade when submitted to mechanical loadings. This degradation leads to a loss in mechanical properties and can induce anisotropy of the material behavior, which…
