Memory in nonmonotonic stress relaxation of a granular system
Kieran A. Murphy, Jonathon W. Kruppe, Heinrich M. Jaeger
We demonstrate experimentally that a granular packing of glass spheres is capable of storing memory of multiple strain states in the dynamic process of stress relaxation. Modeling…

The intertwined roles of particle shape and surface roughness in controlling the shear strength of a granular material
Kieran A. Murphy, Arthur K. MacKeith, Leah K. Roth +1
Both the shape of individual particles and their surface properties contribute to the strength of a granular material under shear. Here we show the degree to which these two aspect…

Edges control clustering in levitated granular matter
Melody Xuan Lim, Kieran A. Murphy, Heinrich M. Jaeger
The properties of small clusters depend dramatically on the interactions between their constituent particles. However, it remains challenging to design and tune the interactions be…
