Molecular adhesion assay for biopolymer systems
Jeremy A. Cribb, Farnaz Fazelpour, David A. Wollensak +4
Molecular adhesion plays a central role in many biological systems, yet existing methods to quantify adhesive strength often struggle to bridge the gap between single-molecule reso…
Community detection forecasts material failure in a sheared granular material
Farnaz Fazelpour, Vrinda D. Desai, Karen E. Daniels
The stability of a granular material is a collective phenomenon controlled by individual particles through their interactions. Forecasting when granular materials will undergo an a…
Controlling rheology via boundary conditions in dense granular flows
Farnaz Fazelpour, Karen E. Daniels
Boundary shape, particularly roughness, strongly controls the amount of wall slip in dense granular flows. In this paper, we aim to quantify and understand which aspects of a dense…
Photoelastic Stress Response of Complex 3D-Printed Particle Shapes
Negin Amini, Josh Tuohey, John M. Long +5
While stress visualization within 3-dimensional particles would greatly advance our understanding of the behaviors of complex particles, traditional photoelastic methods suffer fro…
The effect of grain shape and material on the nonlocal rheology of dense granular flows
Farnaz Fazelpour, Zhu Tang, Karen E. Daniels
Nonlocal rheologies allow for the modeling of granular flows from the creeping to intermediate flow regimes, using a small number of parameters. In this paper, we report on experim…
