Nonlinear force response of modular lattice-based metamaterials
Jochem G. Meijer, Armin Yousefi, Francois Barthelat +1
Lattice-based metamaterials provide lightweight platforms where local instabilities can govern the global mechanical response, enabling applications in energy routing, vibration is…
Effects of reduced gravity on the granular fluid-solid transition: underexplored forces can dominate soft matter behaviors
Paul Sánchez, Karen E. Daniels, Heinrich Jaeger +1
Granular media are soft matter systems that exhibit some of the extreme behavior of complex fluids. Understanding of the natural formation of planetary bodies, landing on and explo…
Hydrodynamic Coupling Melts Acoustically Levitated Crystalline Rafts
Brady Wu, Bryan VanSaders, Melody X. Lim +1
The acoustic levitation of small particles provides a versatile platform to investigate the collective dynamical properties of self-assembled many-body systems in the presence of h…
Acoustically levitated lock and key grains
Melody X. Lim, Heinrich M. Jaeger
We present a scheme for generating shape-dependent, specific bonds between millimeter scale particles, using acoustic levitation. We levitate particles in an ultrasonic standing wa…
Designing Stress-Adaptive Dense Suspensions using Dynamic Covalent Chemistry
Grayson L. Jackson, Joseph M. Dennis, Neil D. Dolinski +5
The non-Newtonian behaviors of dense suspensions are central to their use in technological and industrial applications and arise from a network of particle-particle contacts that d…
Stress-activated Constraints in Dense Suspension Rheology
Abhinendra Singh, Grayson L. Jackson, Michael van der Naald +2
Dispersing small particles in a liquid can produce surprising behaviors when the solids fraction becomes large: rapid shearing drives these systems out of equilibrium and can lead…
