Structure of vibrated powders – numerical results
... issue of interest is the jamming potential of a bridge. A measure of this, in the case of a linear bridge, is its base extension b (see Fig. 4.3); this is the horizontal projection of the ‘span’ of ... made of n particles therefore always rests on n b = n + 2 base particles. For a complex bridge of size n, the number of base particles is reduced (n b < n + 2), because of...
