Modeling of dynamic behaviors of friction
Mechatronics, 2008This paper deals with modeling of dynamic behaviors of friction in the sliding regime. Using a hydraulic cylinder, friction characteristics are experimentally investigated under various conditions of velocity variation. The friction force of the hydraulic cylinder is measured based on the equation of motion using measured values of the pressures in the

Frictional behavior of sputtered TiN
Wear, 1987Abstract In this research, reciprocating sliding experiments were conducted on films of sputtered TiN. The primary emphasis was to evaluate the effect of the applied film thickness on the friction coefficient. Other parameters namely, surface roughness, substrate hardness and applied load were also varied and their effects were studied.

A Review On Friction And Wear Behaviors Of Brake’S Friction Materials
i-manager's Journal on Material Science, 2018The friction brake pads are an important component in the braking system of an automotive. As there is a conversion of kinetic energy to heat energy, temperature of friction pair increases, which in turn cause the coefficient of friction to decrease. This paper gives information about the work done by many researchers to stabilize the coefficient of ...

Frictional Behavior of Textile Fabrics
Textile Research Journal, 2000In this paper, the dynamic response for sliding friction is considered through dynamic models. A new interpretation of the non-uniform sliding phenomenon response is given, based on new topographic details of the fabric surface in front of the leading edge of the sled in movement.

Frictional Behavior in Metalworking Processes
Journal of Lubrication Technology, 1970Frictional behavior in metalworking processes between the tool and the workpiece for unlubricated condition is discussed. The primary aim of the work was to develop means to predict frictional behavior in terms of which metal flow can be better understood.

Frictional behavior of the correlated chain
Die Makromolekulare Chemie, 1972AbstractThe friction coefficient of linear macromolecules is calculated for the correlated chain model using KIRKWOOD's approximation. This model (proposed by SANCHEZ and FRANKENBERG) incorporates a certain long‐range correlation between the segments of a random chain, and contains two parameters: CF, which depends on this correlation (CF = 1 for a ...

Frictional behavior of carbon fiber tows: a contact mechanics model of tow–tow friction
Textile Research Journal, 2014Composite-forming processes involve mechanical interactions at the ply, tow, and filament level. The deformations that occur during forming processes are governed by friction between the contacting tows on the mesoscopic level and consequently between filaments on the microscopic level. A thorough understanding of the frictional properties at the level

Friction and Wear Behavior of Cobalt
Journal of Lubrication Technology, 1975An investigation has been made of the friction and wear behavior of polycrystalline cobalt, over a wide range of rubbing conditions, to establish the general pattern of wear. Evidence has been obtained for the occurrence of three transitions, namely, mild to severe wear at low loads and speeds, severe wear back to mild at higher loads and speeds and a ...

Friction Properties and Frictional Behavior of Rock Separation Planes
1972Since the birth of rock mechanics as a separate branch of science a few decades ago, it has been clear that the laws of continuum mechanics could not be applied to the mechanical behaviour of rock masses near the earth’s surface. The concept of discontinuum mechanics was developed, in which the deformational behaviour of rock masses takes place by ...

The Frictional Behavior of Unlubricated Polyethylene
A S L E Transactions, 1982The unusually low friction and relatively low wear of various types of polyethylene have shown promise for use in naval applications. The investigation concerns friction of polyethylene sliding against itself and against various metal surfaces. The basic materials investigated are all homopolymers having varying degrees of linearity.
