Molecular dynamics simulations of metallic friction and of its dependence on electric currents: development and first results
… dynamics (MD) code to run slider-on-block friction experiments for Al and Cu. Both objects are allowed to evolve freely and show marked deformation despite the hardness difference. We recover realistic coefficients of friction and verify the importance of cold-welding and plastic …

An experimental investigation of the effect of subdivision of contact area on surface temperatures generated by friction
… of surface temperatures generated by dry sliding friction was carried out with the use of an infrared radiometric microscope system that was developed at Virginia Polytechnic Institute and State University. The objective of this study was to investigate the effect of subdividing the …

Infrared measurements of steady-state temperatures and average surface temperature distributions for silver sliding on sapphire
Surface temperatures generated by dry sliding friction were measured with the use of an infrared radiometric microscope system developed at Virginia Polytechnic Institute and State University. Silver was used as the test material because of its resistance to oxide formation. The effects of load, …

A molecular dynamics study of the tribological properties of diamond like carbon
… wear resistance and very low coefficient of friction . We use molecular dynamics (MD) simulations with a reactive force field (ReaxFF) to study the friction and wear between DLC counterfaces, both in comparison to and in contact with steel counterfaces. We show that the tribological …

Settling-Time Improvements in Positioning Machines Subject to Nonlinear Friction Using Adaptive Impulse Control
… the position of machine components subject to friction. Friction dominates the forces affecting fine positioning dynamics. Friction can depend on payload, velocity, step size, path, initial position, temperature, and other variables. Control problems such as steady-state error and limit cycles …
