Resumen:
We simulate the process of compaction under
vertical tapping for a two-dimensional system of particles
deposited in a rectangular box. The particles consist in regular
pentagons and our main objective is to analyze the novel
behavior recently found for the packing fraction as a function
of the tapping strength applied to the system (Vidales et al.
in Phys Rev E 77:051305, 2008).We will relate the behavior
of the number and type of arches,mean coordination number
and number and type of contacts to the peculiar packing density
increase found for increasing tapping strength. Finally,
we present results of an annealed tapping on our packings to
compare the results to the constant tapping protocol. All our
results are compared with the analogous simulations carried
out on disks.
