Postdoctoral Researcher in the Mechanics & Tribology of Triboelectric Nanogenerators (University of Glasgow, UK)

The James Watt School of Engineering is looking for a postdoctoral researcher to contribute to/make a leading contribution to a large international EPSRC funded project looking at the physics and mechanics of triboelectric nanogenerators (or TENGs).  This position will focus on the mechanics and tribology of TENGs and will involve both experimental & modelling work. Of particular interest is modelling and experimental analysis aimed at understanding, predicting and optimising the contact area and charge transfer at triboelectric interfaces.

Gordon Conference on Adhesion - Late July 2023

The Gordon Research Conference on the Science of Adhesion is this summer (23-28 July 2023).  The meeting will be held on the campus of Mount Holyoke College in western Massachusetts and will have more than 20 invited talks from world leaders in the fields of adhesion, soft matter, and materials. This is a great meeting for students and early career researchers to get connected to the community. Poster presentations are strongly encouraged from all participants, and poster abstracts can still be submitted.

Benchmarks for computation contact Mechanics. A collection of problems.

Dear colleagues,

I would like to draw your attention to a recent work we have been doing to set up a library of examples of discrete one-sided contact problems with Coulomb friction. 

The collection of problems can be found here https://github.com/FrictionalContactLibrary/fclib-library  and the C API for writing and listing these files here:

A comment on a hybrid asperity-Persson friction rubber theory by A Emami, S Khaleghian and S Taheri. Friction 9(6): 1707--1725 (2021)

dear collegues, I may be interested to share your views on an "asperity theory" modified Persson's rubber friction contact mechanics theory which I find not clearly motivated and seems to lead to erroneous conclusions ---- but I am also unable to reproduce the results claimed by the authors. The preprint is here, and the original paper attached: https://www.researchgate.net/publication/359392510

Electrical contact resistance and its dependence on applied pressure

The relationships between surface roughness, contact pressure and contact resistance are studied in this work published three years ago.

It is imporant to distinguish between the different conduction mechanisms acting at contacts at different scales, in order to better understand how surface structure and surface chemistry can alter the behaviour of electrical contacts

Contact stiffness of rough surfaces

Contact stiffness of multiscale surfaces by truncation analysis

 

In this concise piece of work, an effective method is shown to gain new understandings into the role of surface structure in the field of contact mechanics. In particular, normal contact stiffness is correlated to parameters of surfaces' fractal dimension and amplitude.

Partial constraint singularities in elastic rods

We present a unified classical treatment of partially constrained elastic rods. Partial constraints often entail singularities in both shapes and reactions. Our approach encompasses both sleeve and adhesion problems, and provides simple and unambiguous derivations of counterintuitive results in the literature. Relationships between reaction forces and moments, geometry, and adhesion energies follow from the balance of energy during quasistatic motion. We also relate our approach to the configurational balance of material momentum and the concept of a driving traction.

Dynamic instabilities of frictional sliding at a bimaterial interface

Understanding the dynamic stability of bodies in frictional contact steadily sliding one over the other is of basic interest in various disciplines such as physics, solid mechanics, materials science and geophysics. Here we report on a two-dimensional linear stability analysis of a deformable solid of a finite height H, steadily sliding on top of a rigid solid within a generic rate-and-state friction type constitutive framework, fully accounting for elastodynamic effects.
