Tribology: Understanding Friction, Lubrication and Wear across the Scales

October 4-8, 2010, Freiburg Germany

The performance of macroscale machines is governed by a variety of nanoscale mechanical and chemical processes at moving interfaces. This makes tribology –the science of interacting surfaces in relative motion— inherently multiscale. Consequently, modeling utilizes the complete MMM toolbox including electronic structure calculations, molecular dynamics, mesoparticle methods and continuum mechanics in order to study the underlying chemical, mechanical and fluidic processes on all length scales. This symposium will form a unique platform that unites modellers and experimentalists to discuss the opportunities and challenges multiscale modelling offers for all kind of tribological issues amongst others:

  • Nanomechanics of asperities and their connection to the macroscale: friction force microscopy, contact mechanics of self-affine surfaces, validity and limitations of macroscopic friction laws, concurrent coupling of scales
  • Lubrication and superlubricity and their relationship to surface and atmospheric conditions
  • Relating nano- and macrofluidics, e.g. connecting atomistics with hydrodynamics to study moving contact lines, topological instabilities, the influence of wall boundary conditions
  • Mechano-chemistry: formation of tribo materials, wear and lubricant degeneration, interfacial modification through tribochemistry
  • Macroscale impact of finite-size effects in nanoasperities, ultrathin lubricant films and nanobridges: nanoplasticity, layering induced phase transitions, thermal fluctuations
