Results from these simulations are shown in Fig. , where no clear trend is visible. In some simulations such as Fig. the double-defect network initially breaks more comprehensively than the edge-removed network, but the situation reverses at the end of the simulation with fewer broken bonds in the doubledefect network. However, in Fig. the opposite occurs. It does not appear that any additional flexibility afforded by the Stone-Wales defect prevents tears from propagating in this network. This is because the extra stress around the defect has a destabilising effect, which cancels out any stability from the flexibility around the defect. We anticipate that future work can further utilise the systematic approach to combining defects for a study of the rupturing properties of amorphous networks.
