Shear modulus and dilatancy softening in granular packings above jamming.
We investigate experimentally the mechanical response to shear of a monolayer of bidisperse frictional grains across the jamming transition. We inflate an intruder inside the packing and use photoelasticity and tracking techniques to measure the induced shear strain and stresses at the grain scale. We quantify experimentally the constitutive relations for strain amplitudes as low as 10(-3) and ...
متن کاملDilatancy in slow granular flows.
When walking on wet sand, each footstep leaves behind a temporarily dry impression. This counterintuitive observation is the most common illustration of the Reynolds principle of dilatancy: that is, a granular packing tends to expand as it is deformed, therefore increasing the amount of porous space. Although widely called upon in areas such as soil mechanics and geotechnics, a deeper understan...
متن کاملJamming V: Jamming in two-dimensional packings
We investigate the existence of random close and random loose packing limits in twodimensional packings of monodisperse hard disks. A statistical mechanics approach— based on several approximations to predict the probability distribution of volumes— suggests the existence of the limiting densities of the jammed packings according to their coordination number and compactivity. This result has im...
متن کاملMaximum entropy and the stress distribution in soft disk packings above jamming.
We show that the maximum entropy hypothesis can successfully explain the distribution of stresses on compact clusters of particles within disordered mechanically stable packings of soft, isotropically stressed, frictionless disks above the jamming transition. We show that, in our two-dimensional case, it becomes necessary to consider not only the stress but also the Maxwell-Cremona force-tile a...
