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, 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.

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.

This chapter introduces contact forces and pressures and its modelling; consequent to this is friction as occurs within the structure and between the constituent components. Various friction or more correctly energy dissipative mechanisms are identified and are grouped into two categories; those that arise because of relative motion between components ...

Friction and Contact Resistance through True Contact Interface
IEICE Transactions on Electronics, 2006The main factor determining for both friction and contact resistance is the true contact area in the contact interface. Contact resistance depends on the size of the true contact area and contaminant films interposed between the contact areas of the interface. Moreover, friction force also depends on the true contact area.

Contact, friction and propulsion
2003A knowledge of Newtonian mechanics is an essential historical and pedagogical foundation for physical theory, but it is also a source of considerable difficulty. It is typically the arena where common sense ideas and reasoning clash with the theory taught1. Not that it is difficult to state or remember the basic law of dynamics for a particle, (F=ma in
