Fig. 6: Fracture in hybrid networks.

a–d Snapshots of a simulation showing propagation of a crack. Bonds are colored according to their force. e Stress-stretch curves are shown for single-edge notch fracture simulations for \(\bar{W}\) = 0.3, 0.6, 10, (from light blue to purple). Crack propagation begins at critical stretch λc, indicated by dashed lines. f The critical stretch λc as a function of \(\bar{W}\) for networks with three levels of permanent bond fractions (black circles, blue triangles, and red squares corresponding to p = 0.42, 0.58, 0.7 respectively). g Images of a crack propagating through a network with bonds colored according to their expected lifetime 1/kd. Note that we re-map atoms to their initial positions, so that only the network topology changes.
