Linear elastic fracture mechanics predicts the propagation distance of frictional slip [PDF]
, 2014 When a frictional interface is subject to a localized shear load, it is often (experimentally) observed that local slip events initiate at the stress concentration and propagate over parts of the interface by arresting naturally before reaching the edge.
