contact mechanics

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.

Dear Colleague,

we are organizing a thematic session on Contact Mechanics (SM02) at the 26th International Congress of Theoretical and Applied Mechanics (ICTAM), Daegu, Korea, August 25-30, 2024, www.ictam2024.org

The deadline for abstract submission is approaching: January 15, 2024.

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.

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

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

MeDiTATe is a European Industrial Doctorate (EID).

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.

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.

I strongly recommend reading these two papers about the recent loss of Ken L Johnson, FRS, Timoshenko Medallist, Gold Tribology Medal, who died the day of my 45th birthday, exactly twice as old.

Dear Colleague,

I kindly inform you that, in the framework of the 14th International
Conference on Fracture (ICF14), to be held in Rhodes, Greece, June 18-23,
2017, we are organizing a mini-symposium on "Fracture and contact in
multiphysics problems: from energy to biological applications".

If you are interested, please submit your two-page abstract through the
ICF14 website (www.icf14.org) by October 31, 2016, selecting our
mini-symposium.

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.

We are proud to announce International Conference on Advances in Applied and Computational Mechanics, which is organized in the honor of  70th birthday of Prof.J.N.Reddy. This is a tribute for his many and lasting contribution to education and research in applied mechanics.

Conference will be held at  WYNDHAM GRAND Hotel, Inciralti Izmir/Turkey during August 5-7, 2015.
