Penetration depth z_stop by total height H for the 10 mm glass bead experiments and simulations. H is the drop height plus the penetration depth. The blue lines in plot (a) represent the data fits to z_stop ~ Hα for the Chrono simulations. The α values for all of the data sets are listed in Table 3. The blue lines in plot (b) represent the penetration depth relationship for the Chrono simulations based on Eq. (3) (i.e., the Poncelet model) and the fit parameters provided in Table 3.
