Role of Frictional Heating in Rubber Friction

Tribology Letters, 2014
The energy dissipation in the contact regions between solids in sliding contact can result in high local temperatures which may strongly affect the friction. This is the case for rubber sliding on road surfaces at speeds above 1 mm/s. I derive equations which describe the frictional heating for arbitrary (non-uniform) motion, taking into account that ...

Friction tearing of raw rubber

Journal of Physics D: Applied Physics, 1984
Sliding raw rubber against a rigid substrate can produce surface cracks in the rubber. The friction-induced rate of crack growth into the rubber bulk was found to be related to the tear energy of the particular grade of rubber under test, irrespective of its specimen geometry. The findings are relevant to the factory processing of raw rubber.

Rubber Friction and Contact Mechanics of Rubber

2010
The nature of friction between rubber and a hard substrate is very important for many technical applications. Rubber friction is significantly different from friction between “hard” substances such as metals or ceramics. It was made evident, most notably through the works of Grosch (1962), that rubber friction is very closely related to internal ...

Friction of Rubber on Ice

Nature Physical Science, 1972
THE friction of rubber on both smooth and rough surfaces has been shown to be related to its viscoelastic properties1. The friction of rubber on ice has not received much attention2–4 and no attempt has been made previously to determine whether the process differs substantially from that on other smooth surfaces.

Friction and frictional rise of wedge sliders on rubber

Wear, 1969
Abstract The friction of wedge sliders on rubber depends surprisingly little on the angle between their leading faces and the rubber surface. Friction remains moderate even when this angle is 90°. A simple theory is put forward which accounts qualitatively for the observed limitation of the frictional force and which also predicts an ...

A Theory of Dynamic Rubber Friction

Rubber Chemistry and Technology, 1963
Abstract Assuming dynamic friction to arise from the shearing and subsequent breaking of distinct bonds between the rubbing members, a general equation is derived for the frictional force which involves the number and average life of the bonds as well as the average time lag between breaking and re-making of a bond at a given site.

Studies of lubricated rubber friction

Tribology International, 1977
Abstract The development of optical interferometry for examining lubricated rubber contacts was described in Part 1 of this article. Part 2 focuses attention on the application of optical techniques to some commonly encountered rubber devices such as fluid seals, wiper blades and road tyres.

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.

Hysteresis and lubricated rubber friction

Wear, 1980
Abstract The effect on the hysteresis coefficient of a scaling down of surface texture is examined theoretically. It is shown that a uniform reduction in scale, where in particular the number of asperities per unit area increases as the square of the scale factor, has no effect on the magnitude of the hysteresis peak although the velocity at which ...
