I want to model a Friction in nano-scale for high contact forces and
low sliding speeds. The base metal is steel and the sliding material
is Aluminum Alloy.I want to find an amount of Elastic and Plastic
deformations at the asperity contacts, separately. Is anyone have an
idea?
You can measure stress as a function of strain and typically
see an elastic to plastic transition. Viz of the system also
helps. If you want some local metric of E vs P, then you
should look at the various per-atom computes and what they
calculate regarding local ordering. E.g. centro/atom or cna/atom.
