Photoelastic Grain Solver v2.0: An updated tool for analysis of force measurements in granular materials
Carmen L. Lee, Lori McCabe, Ben McMillan +6
Photoelastic force imaging is an experimental technique whereby a birefringent granular material is imaged with a polariscope to characterize the internal stress state of a granula…

Pressure Waves During Granular Flows in Varying Gravity Environments
Abigail Tadlock, Lori McCabe, Kerstin Nordstrom
We present results of LAMMPS Molecular Dynamics simulations of 2D gravity-driven flows of 30,000 soft uniform spheres through a vertical silo. We vary the gravitational field (g),…

Experiments and modeling of dust particle heating resulting from changes in polarity switching in the PK-4 microgravity laboratory
Lori S. McCabe, Jeremiah Williams, Saikat Chakraborty Thakur +6
In the presence of gravity, the micron-sized charged dust particles in a complex (dusty) plasma are compressed into thin layers. However, under the microgravity conditions of the P…
