Effect of particle shape and fragmentation on the response of particle dampers
(SAGE Publications, 2014)
A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure. It has been recently suggested that, ...
On and off dynamics of a creeping frictional system
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 ...
Arching during the segregation of two dimensional tapped granular systems Mixtures versus intruders
We present numerical simulations of binary mixtures of granular disks subjected to tapping. We consider the size segregation process in terms of the arches formed by small and big particles. Although arching has been ...
Clogging transition of many particle systems flowing through bottlenecks
(Scientific Reports, 2014)
When a large set of discrete bodies passes through a bottleneck, the flow may become intermittent due to the development of clogs that obstruct the constriction. Clogging is observed, for instance, in colloidal suspensions, ...
First order phase transition during displacement of amphiphilic biomacromolecules from interfaces by surfactant molecules
(Journal of Physics: Condensed Matter, 2014)
The adsorption of surfactants onto a hydrophobic interface, already laden with a fixed number of polymers, is studied using the self consistent field (SCF) calculation method of Scheutjens and Fleer. For polymers having ...
