Fundamental Aspects of Friction and Lubrication 

16-20 April 2012

Fundamental research on friction and lubrication has seen tremendous developments in recent years thanks to improved experimental instrumentation, improved computational methods and novel materials such as graphene. These achievements allow us now to tackle the most important challenges, namely the transition from idealized model systems with single asperities to practically relevant realistic contacts with multiple contact points, elastic deformations, and liquid lubricants.

The goal was opened by an intensive discussion of novel theories of contact mechanics by Martin Müser and Bo Persson. They demonstrated that the classical view of surfaces with a Gaussian distribution of surface roughness is inappropriate in most practical cases and should be replaced by a self-similar distributions. Lionel Bureau and Takeshi Fukuma presented the latest advancements in the characterization of solid liquid interfaces and the arrangement of liquid molecules – including in particular water – in the confined geometry of a sliding contact. One of the highlights of the meeting was definitely the presentation of Clemens Bechinger. His experiments with colloidal model systems allow for unique insights into the ‘atomistic’ processes involved in early stages of plastic deformation. Erio Tosatti chaired a very lively discussion session following this and two other exceptional presentations on novel sliding systems. The academic program was complemented by an impressive lecture by Matthias Scherge from the Fraunhofer Institute for Mechanics of Materials who presented impressive views of mixing flows in nominally solid coatings of bearings.  

Next to the stimulating scientific discussions and the very positive response from many participants, the workshop was definitely successful in presenting the Dutch tribology community and in particular the activities of the newly formed FOM consortium (FOM program Fundamental aspects of friction) to the international scientific community. The young researchers from the consortium established personal contacts amongst each other and with the internationally leading researchers in the field. Moreover, new contacts within the lubrication community lead to new initiatives for a follow-up Lorentz center workshop as well as a new FOM program on solid-liquid interfaces.

With a total of eleven full invited lectures and four short highlight presentations allowed for enough time for both free and coordinated discussions. The discussion sessions, in particular the chaired ones, were very well received. The senior researchers chosen as chair persons did an excellent job at stimulating the discussions. It was also useful to ‘pre-cook’ some discussion by stimulating some of the participants beforehand to bring up certain topics and prepare a few slides specifically for the discussion sessions.
