5th International Conference on Packing Problems: Packing and patterns in granular mechanics

Workshop theme

This workshop will explore elements of sphere packing, pattern formation, and granular mechanics, illuminating the complex behaviour of granular materials and the macroscopic phenomena that emerge from granular systems such as jamming, segregation, mixing, and comminution. Topics also include the theory of optimal packing and its impact on material properties, and the formation of intricate patterns in granular materials driven by a range of external forces. We aim to stimulate discussions and collaborations across the broad field of granular matter and behaviour, fostering advances in their design and manipulation and serving as a platform for cross-disciplinary dialogue, showcasing the emerging challenges and opportunities in Packing, Patterns, and Granular Mechanics. Participants can expect a stimulating and insightful experience, as we collectively explore the intricate relationships between these fascinating areas.

Keynote speakers include: Tomaso Aste (London), Thomas Hales (Pittsburgh), Ken Kamrin (MIT), Farhang Rajai (Montpellier), Bjornar Sandnes (Swansea) and Mark Shattuck (New York).

This is a satellite workshop for the programme “GeomPack: Geometry and packing in material structure and biology”. The workshop will take place at Aberystwyth University.
