The contribution of plastic sink-in to the static friction of single asperity microscopic contacts
Owen Brazil, John B. Pethica, George M. Pharr
We report microscale friction experiments for diamond/metal and diamond/silica contacts under gigapascal contact pressures. Using a new nanoprobe technique which has sufficient dyn…
Extrinsic plastic hardening of polymer thin films in flat punch indentation
Owen Brazil, Johann P. de Silva, John B. Pethica +1
Confined geometries offer useful and experimentally amenable mechanical testing arrangements in which to study the molecular and micro-structural processes which govern plastic yie…
Direct measurement of molecular stiffness and damping in confined water layers
Steve Jeffery, Peter M. Hoffmann, John B. Pethica +3
We present {\em direct} and {\em linear} measurements of the normal stiffness and damping of a confined, few molecule thick water layer. The measurements were obtained by use of a…
