“…Such a interpretation is descriptive, rather than strict, as this mechanical phenomenon reveals greatly nonlinear behaviour and incorporates range of phenomena to date not fully discovered. These phenomena, addressed in the literature, include: static friction, breakaway force and dynamic friction [1][2][3], presliding displacement [4], Stribeck effect [5][6][7][8][9][10][11], hysteretic effects [5,6,9,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], dwell-time and rising breakaway force [30][31][32], and stickslip motion [8,12,13,15,[30][31][32][33]. Recently, the studies also extend to the analysis of synchronization of frictional systems, [34,35].…”
