Frictional Heating of Elliptic Contacts
1994Wherever friction occurs mechanical energy is transformed into heat. The maximum surface temperature associated with this heat generation can have an important influence on the tribological behaviour of the mating components. For band contacts and circular contacts this temperature has already been studied extensively.

Contact Mechanics: Friction and Wear
1998Contact mechanics describes the stresses and the deformations in the neighbourhood of the contact between two pressed bodies. The following examples are given: concentrated and distributed normal and tangential loads, point load, pressure on a circular surface, hertzian contact for normal and tangential loadings.

Contact - Friction of Fuzzy Type. Contact - Friction of Fractal Type
1995The aim of this paper is to introduce fuzzy and fractal friction laws. Fuzzy superpotential laws were first considered by the second author in Panagiotopoulos (1993). The phenomenon is described in terms of a nonconvex superpotential which is appropriately defined and a hemivariational inequality is obtained.

Friction in an elastohydrodynamic contact
Fluid Dynamics, 1976The problem of the movement of a fluid in an elastohydrodynamic contact is examined in cases of high pressures, high displacement velocities, and low characteristic times, taking into account the nonlinear properties of the fluid — dependence of viscosity on pressure, temperature, and displacement velocity. Simple asymptotic formulas are obtained.

In metalworking processes the workpiece is deformed by the contact with the die. The pressure required for deformation generates a stress normal to the die surface. The movement of the workpiece relative to the die surface generates a shear stress at the interface.

Contact and Friction at Nanoscale
Advanced Materials Research, 2008Molecular Dynamics (MD) simulations of indentation and scratch over crystal nickel (100) were carried out to investigate the microstructure evolution at nanoscale. The dislocation nucleation and propagation during process were observed preferably between close-packed planes.

Contact Problems with Friction
2016Contact problems become much more complicated when a kind of friction is taken into account, even in the case that we restrict our attention to 3D problems of linear elasticity. The problems start with the formulation of friction laws, which are of phenomenological nature.

Our understanding of friction and mechanism of energy dissipation has undoubtedly experienced a tremendous profit after the introduction of scanning probe microscopy. Nowadays the tribological response of a sliding asperity can be easily traced down to the atomic scale.

Contact, Support, and Friction
Sociological Perspectives, 1986The networks literature has been bedeviled by an assumption that networks convey supportiveness to the exclusion of conflict. In this article, we discuss a method for distinguishing conflict, support, and simple contact network linkages in surveys.
