On the relevance of the meso-scale in an upscaling approach for granular materials

This paper deals with the interest of upscaling from a meso-scale understand and model the mechanical behavior of granular materials. The meso-domains associated to the meso-scale are defined as closed loops of particles in contact. Six sets of meso-domains with different local textures called “phas...
