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…

Measuring Poisson's ratio during nanoindentation via lateral contact stiffness; issues of slip and plasticity
Owen Brazil, George Pharr
Although Poisson's ratio, v, is a quantity of great importance in materials design, presently, very few methods are available to measure it at small (micrometre) scales and those t…

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…
