In an oscillatory motion both phenomena take place successively, resulting in a stick-slip mode. Since the friction characteristic consists of two qualitatively different parts with a non-smooth transition, the resulting motion also shows a non-smooth behaviour. Thus, stick-slip systems belong to the class of non- swapp careem

"WebDec 29, 2024 · A new frictional mechanism, based on collective stick-slip motion of moir\'e superstructures across polycrystalline two-dimensional material interfaces, is predicted. The dissipative stick-slip behavior originates from an energetic bistability between low- and high-commensurability configurations of large-scale moir\'e superstructures.
