Concrete – execution of works

Recent developments in the constitutive modeling of geomaterials are based on a micro-mechanical description of the physical and chemical interactions involved at the scale of their microstructure. The main constitutive models resulting from this micro-mechanical description are presented in this article. Such models can be either analytical (named "micro-mechanical constitutive relations"), or numerical (built using the discrete element method). Some micro-mechanical elements may also be introduced in more classical phenomenological visco-elasto-plastic relations.
