Symposium description

Mechanical macro- and microscale machines have interfaces in relative sliding motion. Such intimate contact between solids gives rise to friction and wear leading to significant emissions of greenhouse gases and economical losses. Engineers strive to control friction and wear through design of the interface material, lubricants or coatings. The existence of gradients in material properties, such as differences in grain size at surface and in the bulk, as well as the coexistence of fluidic and solid mechanical processes makes tribology - the science of interacting surfaces in relative motion - inherently multiscale. Consequently, modeling requires a multiscale materials modeling approach that includes electronic structure calculations, molecular dynamics, mesoparticle dynamics and continuum mechanics in order to study the underlying chemical, mechanical and fluidic processes on all length scales. This symposium strives to bring together scientists working in these fields. In order to make contact to experiments where ever possible, experimentalists are strongly encouraged to actively participate with talks.

Specific topics of interest include, but are not limited to:

  • Surface mechanochemisty, including surface microstructure evolution and formation of intermixed surface layers
  • Lubricant and additive function
  • Colloidal sliding systems
  • Slip and detachment of interfacial sliding fronts
  • Non-adiabatic electronic processes, electronic friction, non-contact friction
  • Concurrent coupling of quantum, atomistic, mesoscale and continuum techniques in solid surface mechanics and lubrication
  • Influence of roughness on friction, wear and adhesion on many scales
  • Scanning probe techniques
Confirmed Invited Speakers

  • Naruo Sasaki (Seikei University, Japan)
