3.4. Conclusions
A better understanding of the behavior of granular materials through a physical
multiscale approach appears to be very fruitful for the rational use of these materials
in civil engineering works. Local phenomena within the material, such as friction at
grain contact and grain breakage, are integrated, first, at the scale of granular
assembly and, second, at the scale of the whole engineering work. This approach
allows us to solve difficult problems, such as the development of shear bands and
