Designing avalanche net structures stands as a particular complex problem in as much as it requires to model the mechanical interaction between unusual materials, namely an heterogeneous multi-phases time-changing material and a flexible- open structure. This review paper shows the relevance of a multiscale approach that makes it possible to determine forces acting in the different parts of the structure by taking into account micro-structural processes occurring within the snowpack. For this purpose the micro-directional model is used to describe the behavior of snow as an assembly of bonded ice grains. Afterwards, a coupled analysis of both the net structure and the snow mantel is developed through a Lagrangian- Discrete approach. Some computational results are finally commented.
