[1Ba03] The dynamic stiction mode as a different description of macroscopic static friction

*Ken Nakano¹ (1. Yokohama National University)

It is common knowledge that there are two types of solid friction: "static friction" and "kinetic friction". However, the authors have found that through mechanical analysis of a sliding system with a geometric asymmetry, the rotation of the kinetic friction vector produces apparent static friction. From the point of view of this "dynamic stiction mode", using only purely mechanical terms, "stick-to-slip transition" can be described as "overdamping-to-underdamping transition".
