suitable for the study of rupture. This is because rupture is a localised phenomenon, especially for a polymer network where separated polymers have minimal interactions. Those damage metrics are shown in Fig. for the rupture shown in Fig. , and Fig. for a network with weaker bonds. The average coordination number when rupture begins in Fig. is 2.95, compared to 3.00 for an idealised hexagonal network leading to an average number of edges per polygon of 6.19 as opposed to 6.
