   • 2015, Vladislav A. Yastrebov, “Sliding without slipping under Coulomb friction: opening waves and inversion of frictional force”, in arXiv‎^[1]:

     We demonstrate that if the coefficient of friction is high enough, the sliding localizes within stick-slip pulses, which transform into opening waves propagating at intersonic speed in the direction of sliding or, for high Poisson's ratios, at supersonic speed in the opposite one.
