Pattern Formation in Vibrated Granular Layers
Friday, January 26, 1996 4:00 p.m. Paul B. Umbanhowar Department of Physics The University of Texas at Austin Pattern formation in thin layers of vertically vibrated granular material has been investigated as a function of oscillation frequency, acceleration ampliĀtude, and layer thickness. Above a critical acceleration of approximately 2.5g (where g is the acceleration due…
