Viscous-inertial transition in dense granular suspension
Franco Tapia, Mie Ichihara, Olivier Pouliquen +1
Granular suspensions present a transition from a Newtonian rheology in the Stokes limit to a Bagnoldian rheology when inertia is increased. A custom rheometer which can be run in a…
The influence of surface roughness on the rheology of immersed and dry frictional spheres
Franco Tapia, Olivier Pouliquen, Elisabeth Guazzelli
Pressure-imposed rheometry is used to examine the influence of surface roughness on the rheology of immersed and dry frictional spheres in the dense regime. The quasi-static value…
Wave localization in strongly nonlinear Hertzian chains with mass defect
S. Job, F. Santibanez, F. Tapia +1
We investigate the dynamical response of a mass defect in a one-dimensional non-loaded horizontal chain of identical spheres which interact via the nonlinear Hertz potential. Our e…
Experimental evidence of shock mitigation in a Hertzian tapered chain
Francisco Melo, Stephane Job, Francisco Santibanez +1
We present an experimental study of the mechanical impulse propagation through a horizontal alignment of elastic spheres of progressively decreasing diameter , namely a tapere…
