We review the historical and modern understanding of the most basic equation of friction, Amontons' law, which describes phenomena that were already understood and studied by Leonardo da Vinci 500 years ago. This law states that for any two materials the (lateral) friction force is directly proportional to the (normal) applied load, with a constant of proportionality, the friction coefficient, that is constant and independent of the contact area, the surface roughness, and the sliding velocity… Expand
Systematic Breakdown of Amontons' Law of Friction for an Elastic Object Locally Obeying Amontons' Law
The macroscopic static friction coefficient, which corresponds to the onset of bulk sliding of the object, decreases as pressure or system length increases, and is consistent with the results of certain previous experiments. Expand
Sliding friction: From microscopic contacts to Amontons’ law
Most engineers describe sliding friction using the friction coefficient, the ratio of frictional force to normal force. While this proportionality is very simple, its origin is not trivial at all andExpand
Sliding friction between polymer surfaces: a molecular interpretation.
This work evaluates a much smaller friction for a cross-linked polymer under the assumption that the junctions are effectively immobile, in agreement with the experimental results of Maeda et al. Expand
Molecular probes reveal deviations from Amontons’ law in multi-asperity frictional contacts
A new contact detection method is presented to show that the law of Amontons’ law is broken because asperities interact and deform in the contact area to change it, thereby also changing the friction force. Expand
Viscous friction of hydrogen-bonded matter.
It is shown that friction between hydrogen-bonded matter obeys in the biologically relevant low-velocity viscous regime a simple law: the friction force is proportional to the number of HBs, the sliding velocity, and a friction coefficient γ(HB). Expand

Findings reveal the boundary of validity of Amontons' law, unify negative and giant friction coefficients, rationalize the experimentally observed anisotropy of nanofriction, and are universal when vdW interactions are crucial, all of which are helpful to establish a comprehensive picture of nan ofriction.

Load and Time Dependence of Interfacial Chemical Bond-Induced Friction at the Nanoscale.
This work shows that for nanoscale ICBI friction of silica-silica interfaces, aging increases approximately linearly with the product of the normal load and the log of the hold time, which implies that the average pressure, and thus the average bond formation rate, is load independent within the accessible load range.

Abstract Friction at different force, length, and time scales is of great interest in tribology. The mechanical, chemical, and physical (atomic) interactions, each operating at their own force andExpand
Atomic-Scale Friction
Friction is a critical issue and progress in the field has been hindered by the complex mechanical, physical, and chemical interactions that occur when two surfaces slide against each other, often inExpand
