Théorique, numérique
The objective of the internship is to study numerically the stability of heaps of entangled fibres under gravity, and investigate the impact of microscopic quantities (length and natural curvature of the fibres, friction between fibres) on the limit angle attainable with static macroscopic heaps. These numerical experiments will in particular help identify the relevant non-dimensional microscopic parameters which control the macroscopic static friction of the medium.
