Dynamic and programmable cellular-scale granules enable tissue-like materials
Yin Fang, Endao Han, Xin-Xing Zhang +26
Tissue-like materials are required in many robotic systems to improve human-machine interactions. However, the mechanical properties of living tissues are difficult to replicate. S…
Intrusion into granular media beyond the quasi-static regime
Leah K. Roth, Endao Han, Heinrich M. Jaeger
The drag force exerted on an object intruding into granular media can depend on the object's velocity as well as the depth penetrated. We report on intrusion experiments at constan…
Constant speed penetration into granular materials: drag forces from the quasistatic to inertial regime
Leah K. Roth
Predicting the force exerted on an object as it penetrates a granular medium is of interest in engineering, locomotive, and geotechnical applications. Current models of granular dr…
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…
Optimizing Packing Fraction in Granular Media Composed of Overlapping Spheres
Leah K. Roth, Heinrich M. Jaeger
What particle shape will generate the highest packing fraction when randomly poured into a container? In order to explore and navigate the enormous search space efficiently, we pai…
