Effects of interparticle cohesion on the collapse of granular columns
The presence of interparticle cohesion can drastically change the behavior of granular
materials. For instance, powders are challenging to handle, and one can make a sandcastle …

Buckling instability in a chain of sticky bubbles
CL Lee, K Dalnoki-Veress - Physical Review Research, 2024 - APS
A slender object undergoing an axial compression will buckle to alleviate the stress.
Typically the morphology of the deformed object depends on the bending stiffness for solids …

Two-dimensional spreading of frictionless adhesive oil droplets
J Hoggarth, K Dalnoki-Veress - Soft Matter, 2023 - pubs.rsc.org
When sand flows out of a funnel onto a surface, a three dimensional pile that is stabilized by
friction grows taller as it spreads. Here we investigate an idealized two dimensional …

Buckling instabilities in moving chains of bubbles
C Lee, K Dalnoki-Veress - APS March Meeting Abstracts, 2023 - ui.adsabs.harvard.edu
When slender structures are subjected to a compressive force, they will buckle and bend as
mediated by the bending modulus of the solid material or the viscosity of the liquid. Here, we …
