Hyperstaticity and loops in frictional granular packings
Antoinette Tordesillas, Edward Lam, Philip T. Metzger
The hyperstatic nature of granular packings of perfectly rigid disks is analyzed algebraically and through numerical simulation. The elementary loops of grains emerge as a fundamen…
Ageing of a granular pile induced by thermal cycling
Thibaut Divoux, Ion Vassilief, Hervé Gayvallet +1
Here we show that variations of temperature, even of a few degrees in amplitude, induce the ageing of a granular pile. In particular, we report measurements of physical properties…
Craters Formed in Granular Beds by Impinging Jets of Gas
Philip T. Metzger, Robert C. Latta, Jason M. Schuler +1
When a jet of gas impinges vertically on a granular bed and forms a crater, the grains may be moved by several different mechanisms: viscous erosion, diffused gas eruption, bearing…
The Flow Of Granular Matter Under Reduced-Gravity Conditions
Paul G. Hofmeister, Jürgen Blum, Daniel Heißelmann
To gain a better understanding of the surfaces of planets and small bodies in the solar system, the flow behavior of granular material for various gravity levels is of utmost inter…
Laboratory studies of ice-particle collisions in Saturn's dense rings
Daniel Heißelmann, Jürgen Blum, Kristin Wolling
In this work, we report on microgravity studies of particle ensembles simulating ice-particle collisions in Saturn's dense main rings. We have developed an experimental method to s…
Towards a Dynamical Collision Model of Highly Porous Dust Aggregates
Carsten Güttler, Maya Krause, Ralf J. Geretshauser +2
In the recent years we have performed various experiments on the collision dynamics of highly porous dust aggregates and although we now have a comprehensive picture of the microme…
