Distinguishing deformation mechanisms in elastocapillary experiments
Shih-Yuan Chen, Aaron Bardall, Michael Shearer +1
Soft materials are known to deform due to a variety of mechanisms, including capillarity, buoyancy, and swelling. In this paper, we present experiments on polyvinylsiloxane gel thr…
Gradient Induced Droplet Motion Over Soft Solids
Aaron Bardall, Shih-Yuan Chen, Karen E. Daniels +1
Fluid droplets can be induced to move over rigid or flexible surfaces under external or body forces. We describe the effect of variations in material properties of a flexible subst…
Well-posed continuum equations for granular flow with compressibility and -rheology
T. Barker, D. G. Schaeffer, M. Shearer +1
Continuum modelling of granular flow has been plagued with the issue of ill-posed equations for a long time. Equations for incompressible, two-dimensional flow based on the Coulomb…
Deformation of an Elastic Substrate Due to a Resting Sessile Droplet
Aaron Bardall, Karen E. Daniels, Michael Shearer
On a sufficiently-soft substrate, a resting fluid droplet will cause significant deformation of the substrate. This deformation is driven by a combination of capillary forces at th…
Elastocapillary deformations on partially-wetting substrates: rival contact-line models
Joshua B. Bostwick, Michael Shearer, Karen E. Daniels
A partially-wetting liquid can deform the underlying elastic substrate upon which it rests. This situation requires the development of theoretical models to describe the wetting fo…
Shear-driven size segregation of granular materials: modeling and experiment
Lindsay B. H. May, Laura A. Golick, Katherine C. Phillips +2
Granular materials segregate by size under shear, and the ability to quantitatively predict the time required to achieve complete segregation is a key test of our understanding of…
