Static Friction and the Law of Rubber Friction

Rubber Chemistry and Technology, 1963
Abstract a) The true static friction of vulcanized rubber is in practice immeasurably small (equal to zero, according to theory). b) The static friction as usually determined is an initial friction force. c) The initial friction force is equal to the sliding friction force in accelerated movement.

An elastoplastic friction compensator with improved static friction behavior

2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2016
Mahvash and Okamura's elastoplastic friction compensator is one of successful friction compensators for robotic joints with compliant transmissions. A limitation of the scheme is that, in the static friction state, the compensator continues commanding non-zero output force, which hampers the system's reaction to external forces.

Static and Sliding Friction in Feedback Systems

Journal of Applied Physics, 1953
One of the most common nonlinearities encountered in servomechanisms design is the friction phenomenon in electromechanical systems. Conventional linear theory fails to predict its effect upon system performance. This paper extends familiar techniques to the treatment of friction nonlinearity in servosystems.

The Laws of Static Friction

Textile Research Journal, 1953
The relation F = aRn between the frictional force and normal reaction is found to hold for fibers, and it is proposed to replace Amontons' law by this form. The friction index, n, is found to lie between 0.80 and unity. The significance of this relation is discussed in terms of the cohesion theory of friction.

Relation between the static-friction and slipping-friction coefficients

Russian Engineering Research, 2015
A method of establishing the relation between the static-friction and slipping-friction coefficients of a specific pair of materials is proposed. The theoretical basis of the method is outlined, and the corresponding device is described.

Toward Zero Static Friction at the Microscale

Physical Review Letters
Static friction, a ubiquitous physical phenomenon, plays a significant role in natural processes and industrial applications. Its influence is particularly notable in the field of controlled micromanipulation and precision manufacturing, where static friction often exceeds kinetic friction and leads to material damage and unpredictable behaviors.

Teaching Mechanics: Inequalities in Statically Indeterminate Static Friction Problems

2019
In this contribution, we provide a mathematical treatment of the inequality systems arising from two toy examples of statically indeterminate, static friction problems with multiple contact planes. Both examples illustrate general phenomena that are not covered by introductory textbooks.

Static-to-sliding friction measurements

2012
Static friction is a phenomenon mainly regarded as related to frictional joints within static mechanics. At the onset of sliding in mechanical contacts, static friction determines the initial resistance against motion, which subsequently is superseded by sliding friction.
