The testing procedures and reported tribological performance of polymer gears, which are
seeing ever-increasing use by industry, still lack consistency and detail. One of the key …

The time for which each contacting body is exposed to a tribological contact affects its
interface temperature, third-body and tribofilm formation, and, as a result, the overall …

The multi-asperity contacts between two nominally flat surfaces were studied experimentally
with sub-micron resolution, to provide detailed experimental information that is seriously …

How the contact behaviours of steel engineering surfaces with different roughnesses (R a=
0.1, 0.6 and 1.0 µm) are affected by the asperity work-hardening and the deformation regime …

In any attempt to theoretically calculate the real contact area for 3D engineering surfaces, a
criterion is needed to identify the relevant asperity-peaks that carry the load in tribological …

The real contact area and asperity deformations are studied in an experiment with
submicron resolution for different materials and roughnesses. When the contact pressure is …

We present apparatus that allows in-situ optical measurements of the evolving real contact
area between a rigid glass and a deformable Al6026 surface with 700 nm of lateral and 20 …

We demonstrate the influence of edge effects on the photothermal-induced phase shift
measured by a homodyne quadrature laser interferometer and compare the experiments …

Many researchers from scientific and industrial fields have devoted their efforts to the laser
interferometer, aiming to improve the measurement accuracy and extend the practical …

Purpose A nondestructive, noncontact approach for the estimation of elastic parameters of
fully clamped thin sheet is presented in current work. Frequency response of pulsed laser …
