How do I use this calendar?

You can click on an event to display further information about it.

The toolbar above the calendar has buttons to view different events. Use the left and right arrow icons to view events in the past and future. The button inbetween returns you to today's view. The button to the right of this shows a mini-calendar to let you quickly jump to any date.

The dropdown box on the right allows you to see a different view of the calendar, such as an agenda or a termly view.

If this calendar has tags, you can use the labelled checkboxes at the top of the page to select just the tags you wish to view, and then click "Show selected". The calendar will be redisplayed with just the events related to these tags, making it easier to find what you're looking for.

Towards multiscale modelling of boundary lubrication

Hannes Holey, Karlsruhe Institute of Technology

 

Friction and lubrication are inherent multiscale problems, particularly when the gap between contacting bodies is on the order of molecular interaction length scales. Modelling lubrication across scales beyond purely sequential approaches has so far remained elusive. In this talk, I will present a reformulation of the classical lubrication equations that principally allows straightforward coupling between continuum and molecular models. Furthermore, I will show how fluctuations of collective variables in confined fluids relate to the continuum description, giving rise to slip length measurement in equilibrium molecular dynamics (MD), as well as the description of anomalous sound transport in low aspect ratio fluidic systems. The last part of the talk will be devoted to an outlook on incorporating MD-informed constitutive relations into the existing continuum framework with the help of machine learning, leading to a concurrent multiscale method.
