abstract = {A prominent spatiotemporal failure mode of frictional
systems is self-healing slip pulses, which are propagating
solitonic structures that feature a characteristic length.
Here, we numerically derive a family of steady state slip
pulse solutions along generic and realistic rate-and-state
dependent frictional interfaces, separating large deformable
bodies in contact. Such nonlinear interfaces feature a
nonmonotonic frictional strength as a function of the slip
velocity, with a local minimum. The solutions exhibit a
diverging length and strongly inertial propagation
velocities, when the driving stress approaches the
frictional strength characterizing the local minimum from
above, and change their character when it is away from it.
An approximate scaling theory quantitatively explains these
observations. The derived pulse solutions also exhibit
significant spatially-extended dissipation in excess of the
edge-localized dissipation (the effective fracture energy)
and an unconventional edge singularity. The relevance of our
findings for available observations is discussed.},
