Abstract
In this paper we present experimental results concerning
the compaction of a granular assembly of spheres under periodic shear
deformation. The dynamics of the system is slow and continuous when
the amplitude of the shear is constant, but exhibits rapid evolution
of the volume fraction when a sudden change in shear amplitude is
imposed. This rapid response is shown to be uncorrelated with
the slow compaction process.
