Frictional sliding, oscillations and energy balance in the presence of asymmetric friction

Asymmetric friction refers to the case of different friction forces resisting sliding in opposing directions. This research investigates the effect of asymmetric friction on the features of sliding over friction contact. Parametric analyses are conducted on different spring-block models to understand the motion and energy transfer. Asymmetric friction acts as a mechanical rectifier that can emerge in both natural and engineering systems. This study provides a theoretical basis for the development of novel hybrid- and metamaterials for energy harvesting from parasitic oscillations as well as for monitoring of local sliding in anisotropic(e.g. layered) materials and rocks.
