Some Hamiltonian models of friction [PDF]
Journal of Mathematical Physics, 2011 Mathematical results on a model describing the motion of a tracer particle through a non-interacting Bose-Einstein condensate are described. In the limit of a very dense gas and for a very large particle mass, the dynamics of the coupled system is determined by classical nonlinear Hamiltonian equations of motion.

Multi-physics simulation of friction stir welding process [PDF]
, 2009 Purpose: The Friction Stir Welding (FSW) process comprises of several highly coupled (and non-linear) physical phenomena: large plastic deformation, material flow transportation, mechanical stirring of the tool, tool-workpiece surface interaction ...

Experimental comparison of five friction models on the same test-bed of the micro stick-slip motion system [PDF]
Mechanical Sciences, 2015 The micro stick-slip motion systems, such as piezoelectric stick-slip actuators (PE-SSAs), can provide high resolution motions yet with a long motion range. In these systems, friction force plays an active role.

Nanofriction behavior of cluster-assembled carbon films [PDF]
, 2002 We have characterized the frictional properties of nanostructured (ns) carbon films grown by Supersonic Cluster Beam Deposition (SCBD) via an Atomic Force-Friction Force Microscope (AFM-FFM). The experimental data are discussed on the basis of a modified

Study on asymmetrical cold rolling considered sticking friction
Journal of Materials Research and Technology, 2020 A new model considered the sticking friction for analyzing the asymmetrical cold rolling process is proposed by the slab method. This friction model is composed of the Coulomb friction model and yield shear stress.
