Time evolution of the mean coordination of the six cases with: (a) v = 10 m s⁻¹, where all outcomes are adhesion, (b) v = 40 m s⁻¹, where all outcomes are fragmentation. The values of the final mean coordination number 〈C〉_f for each case are reported in the same order as the legend (from top to bottom): (a) 3.03, 3.29, 2.69, 2.68, 2.72, 3.02; (b) 2.66,2.76,1.8,1.81,2.0, and 2.25.
