"When S>µmg, the velocity of the mass is ever accelerated, and when S<µmg, it is ever decelerated until the mass comes to standstill." However, if the base surface is in vibration in the horizontal plane, and if some condition is fulfilled, the mean velocity of the mass can be kept constant as if there exists some viscous resistance. This phenomena may be called as "Frictional Viscosity." The mean velocity thus observed has, in general, components not only in the direction of S but also in the lateral direction to it.}, pages = {171--176}, title = {On Frictional viscosity in vibrating systems}, volume = {19}, year = {1968} }
