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.

MARKET FRICTIONS, SAVINGS BEHAVIOR, AND PORTFOLIO CHOICE
Macroeconomic Dynamics, 1997We examine a decision theoretic model of portfolio choice in which investors face income risk that is not directly insurable. We consider the sensitivity of savings and portfolio allocation rules to different assumptions about utility, the stochastic process for income and asset returns, and market frictions (transactions costs and short-sale ...

Frictional behavior of commercial graphites
Carbon, 1974Abstract Coefficient of friction of commerical grades of polycrystalline graphites against deoxidized high phosphorus copper has been measured in an inert atmosphere at 10−5 mm Hg pressure. Graphites with large particles have a coefficient of friction of 0·48 at room temperature and of 0·35 at about 1000°C. Finer particle sized graphites have a lower
