Abstract

We describe a friction model to link the continuum-based shear and plowing method of Bowden and Tabor with the atomistic processes that occur at the nanoscale. We show that the interfacial shear component can be modeled via dislocation drag at the interface, and the plowing in terms of power-law creep. We show that without empirical friction measurements, this approach has a strong predictive power for the interfacial sliding of crystalline materials.
