Some computational issues in the elasto-plastic modelling of snow

In this work, the Authors describe some of the still open and unsolved questions related to the constitutive modeling of snow with reference to Elasto-Plastic approaches. Furthermore, some suggestions on possible computational solutions through Finite Element tools are highlighted. The goal is twofold: first, we try to summarize the current state-of-the-art of FE analysis on snow; and second, we suggest some possible research directions and computational solutions to improve the existing mechanical models.
