• Apparent mass during silo discharge Nonlinear effects related to filling protocols 

    Peralta, Juan Pablo; Aguirre, María; Geminard, Jean Christophe; Pugnaloni, Luis (Elsevier, 2017)
    We study the evolution of the force exerted by a granular column on the bottom surface of a silo during its discharge. Previous to the discharge, we prepare the system using different filling procedures: distributed, i.e. ...
  • On and off dynamics of a creeping frictional system 

    Blanc, Baptiste; Geminard, Jean Christophe; Pugnaloni, Luis (Springer, 2014)
    We report on the dynamics of a model frictional system submitted to minute external perturbations. The system consists of a chain of sliders connected through elastic springs that rest on an incline. By introducing cyclic ...
