Simulation of Inhomogeneous Columns of Beads under Vertical Vibration
Figure 4
At , , and (the same as in
Figure 3), but placing 5 heavier spheres (mass ) on the bottom
and 5 spheres (mass ) on the top of
column with mass ratio the spheres follow
chaotic trajectories, as indicated in frequency spectrum of the center-of-mass
motion.
